Boeing 747s Still Use Floppy Disks to Get Critical Software Updates

It’s been approximately 12 million years since most of us last used a floppy disk, but apparently, the antiquated tech still plays a critical role in delivering software updates to Boeing’s 747-400 planes. The discovery comes courtesy of cybersecurity firm Pen Test Partners and was initially spotted by The Register. As part of this year’s virtual DEF CON hacker conference, Pen Test Partners showed off a video walkthrough of a British Airways 747 after the airline decided to retire its entire… ( さらに...

People seem surprised that an aircraft designed in the 1980s uses technology from the 1980s.

Exactly... Why upgrade or Fix what is not broken... The USB is still takes about 30 minutes. It is not the speed or the technology of how fast something can push the data in, but how fast it can take it. In experience, using Floppy or USB has 1 big difference... Swappy Floppy Disks or waiting on a USB... the only advantage I see over USB is that you can start 1 and go to the next, come back 30 minutes later. Surprisingly, Both take about the same amount of time to update. USB means I can do something else, vs waiting to swap to the next disk, and that is the only advantage.

if your computer takes 30min to DL 1.44mb from a USB stick. well you really get scammed.

Downloading from a USB is way faster than a floppy whatever the size of data.
Robert Cowling -1
Generally, yes. But it depends on what the system is doing during the download time. If it's saving old configurations, and wiping memory, etc, it can take a bit of time, depending on how long that whole process takes. I had a Windows Server update take over 4 hours. Microsoft said, when I called, 'Yeah, that one can take a while to install, depending on what you use the server for'. FOUR HOURS? That is an eternity when you're waiting for it to finish during a work day. Yikes...

floppies can't be hacked or given a virus = unless it was already on the disk. I still use my 8.75" disks

Really? An 8-3/4" drive? Must have come from one of those flying saucers out in Area 51 then because the closest we got to that with standard disks was 8" Now we did move on to 5-3/4" after those, so maybe that's confusing you. As to your "can't be hacked or given a virus" claim, lordy, that was a good laugh. I haven't chuckled like that in ages!
joel wiley 3
Back when 8" floppies were used, a virus was too big to fit on one.
lynx318 1
Floppies can be easily accidentally erased. Also over 22,000x 1.44mb floppys equal 1x 32gb flash drive. Storage is a pain!
F. M. 2
If you slide the 3.5 inch diskettes' built-in read-only tab into place, it can only be erased by coming too close to magnet. I would hope all diskettes sent to the mechanics would have that tab already set to read-only.
Robert Cowling 0
More than that. The chuck plate can become detached from the mylar disk part. I found a whole box of vintage (NOS) floppy disks. The kind that came in the translucent colors, remember. I stuck one into a portable drive I still have, and got nothing. Weird, huh. I ejected it, and put int he next one. Same story. As if there was no disk in the drive. I tried another one, and nope, same story. How could a whole box of those cool looking disks be bad, and bad in what way? I opened the shutter on one, and started trying to spin the chuck plate. Yeah, spun free. OMG!!! The glue went bad.

I started thinking of all the people that had precious pictures, and other stuff on those, and all the installation disks that were now, likely bad. Wow...

PLUS! If you get anything in between the disk and the fabric liner inside the plastic case (many had fabric, some used plastic sheets) it's being scrubbed clean over a short amount of time.

I'm not surprised they used floppies. Doing a change would have likely been a long drawn out process for testing and approval, subject to dust/dirt/grime, and floppies were working. Switching to wifi would have been problematic on so many levels too. Some planes, I understand, have/had thermal printers installed for data 'on the go' as well. No computer screens to scroll like I'm sure they have now.

But what do the 800's use for updates?
lynx318 0
Magnetic erasure is what I was referring to and as for the tab, heard of sticky tape, works well.

neither can usb sticks or dvd's or whatever medium you use in the future.
What an idiotic comment.
Dmitriy Sheremetyev 3
CDs, DVDs, Blu-Rays, tapes and other 'true' media cannot be hacked, but USB sticks actually have a controller with it's own firmware storage that could be hacked to load a virus on it - even if there is nothing on the 'storage' part of the memory. And yes, viruses like that actually exist out there. A USB stick is basically both media and reading/writing device for it all in one. Using antiquated technology is not the best way to safeguard your systems, IMHO, but don't assume people do not know what they are talking about.

@ThinkingGuy stated "People seem surprised that an aircraft designed in the 1980s uses technology from the 1980s." It should still be using Loran navigation?
F. M. 2
Correct me if I'm wrong, but the 747 in general (maybe not the model 400 specifically) was designed in the 1960's for a 1969 debut.
Brian Anderson 2
Nor were they using floppy disks to load nav data in 1969. In 1969 pilots still had to know how to navigate.

The most advanced Flight Management Systems were installed in the Apollo spacecraft at the time. And even for them, the sextant was still their primary source of positioning data.

Don't drop the deck! A-h-h-h-h-hh!
F. M. 1
Didn't you sequence the cards in columns 73-80 like all good programmers were told to do? That way, if you dropped them, you could take them to an IBM 704 card sorter and have them put back in the correct sequence. :-)

Don Whyte 1
In tech school in the 1960's we used IBM cards ("Hollerith cards") in our programming classes. One of our classmates would sneak a card into the middle of someone's program deck and when got your program printout there would be a line "there is but one God and Mohammed is his prophet" WTH??
F. M. 1
My college 20-hours/week work/study job was keypunching information for the college's admissions/records department. I learned what drum cards were and how to set them up. Not exactly a "resume enhancer", but it did help me hone my basic typing skills so that when I gained access to a TTY machine, I was able to program a lot quicker because of my better-than-average typing skills.
Robert Cowling 2
And I worked at a big-ten university as a programmer. They were about to dump the old rubber cement paper student records that were housed in a massive basement of the admin building. At the beginning of every term, the 'computer' spit out the classes you needed, and you had to go pick up your cards, then lay them out and see if the schedule made any sense, and often it didn't. (Get across campus in 5 minutes for a class, only to be on the other side in 5 for the next one? Or not get that last class you needed to graduate) So, after you pulled your cards, and realized the crap you were dealt, you had to go to 'the pit', and like in the stock market, bid for classes you needed and the times you needed them in. If you were lucky, you got what you wanted. If you were unlucky, the one class you need for your Masters degree, which is only offered once a year, would be full, and no one wanted to change for anything you were dealt. Often, I heard, some people would link up with others and try to pull off a 3 or 4 person trade, it was that desperate.

And, yes, transcript requests were copies of the rubber cement glued papers in your file. Hopefully not many of the classes and grades fell off, which happened rather frequently...

On vacation once, I ran into someone who went there, and they started regaling everyone about what an experience it was to be in 'the pit', and have someone with the class you need, but you have nothing they want, and they won't trade. I said, 'Oh, that was xxxx university. Well, I'm on a project to kill the pit.' They came over and hugged me. Odd, but...

Didn’t the old Soviet Union use tube technology in their aircraft while the US & others went to solid state transistors? It was my understanding they felt tube technology was the way to go if EMP from a nuke fried everyone else’s up to date technology

And old cars had phonographs in the dashboard. You inserted a full size LP record in a wide slot. It didn't make it 'cutting edge'. It was old junk. *shrug*

I was amused by the "poor engineer" bit. This is obviously someone who's never worked on airplanes. In the ten years I did so, I loved getting this job. It's clean, you're out of the cold wind and rain, and you get to sit on a comfortable chair while the data is loading. What could be better?
sparkie624 6
Why is this news? I mean really.... The Floppy Disks are still used in all older boeing systems, even though most of those planes are no long flying in the US. Most of the CRJ-200's still use floppy even though many have been upgraded to USB. I have upgraded many of the past couple of Decades.

The early 737-300s were updated but TAPE DRIVES. They were all updated to 3 1/2 inch floppy drives.
sparkie624 4
Advanced 200's as well that had FMS, but back then, not many had FMS... I have done many tape updates... UGH.. that was pretty bad.... Floppy was a HUGE improvement over tape.

The Russians deliberately kept many key systems on Vacuum tubes rather than transisters, presumeably because they would not be affected by an EMP.

I recall standing inside the very first 747 fuselage shell at the still-under-construction hangar at Paine Field, in Everett, WA, in 1967 and saying to myself: 'you could play a football game inside here'. It's exciting to know that I played a small part in this historic series of aircraft.

Oh 3.5” floppy. At least it’s not a 8” drive. If it ain’t broke don’t fix it. I believe the 747-800 was upgraded.
F. M. 1
Call me a Luddite, but I always had a problem calling the 3.5 inch diskettes "floppies". To me, the 5.25 inch an 8 inch ones were the true floppies because they at least would bend. A 3.5 inch diskette is "firmie", not a "floppy" due to its hard plastic shell.

But any paper tissue for your nose is a Kleenix.
Sometimes the name is a label rather than a description.
SkyAware123 1
True. The equipment uses it can't use anything with more capacity anyways since the software to be updated is also small. The only issue I can see is if floppies are no longer available. They don't last forever and probably haven't been made in quite a while. Even sitting on a shelf, new , they won't last.
Randy Medors 2
Untrue, 3.5" diskettes are still available. A simple Google or Amazon search will tell you that. However they are much more expensive than they used to be back in the day.
stardog01 3
None of the comments so far have mentioned the video in that article. Th video is tour of some behind-the-scenes areas of the 747. They show the avionics bay below the lower passenger deck, and it looks just like a server room. The video also discusses the technology of the electronics, etc. It's fascinating.
birdbrainz 6
Yawn. What else is new? Wasn't it Al Qaeda that was using floppy disks post 9/11 to communicate, thus making it extremely difficult for us to eavesdrop? If it ain't broke...
SkyAware123 3
Don't see how a floppy disk is harder to 'eavesdrop' on than a usb stick.
Robert Cowling 4
"Sorry for the delay folks, but the plane blue screened, and we have to reboot. The diskette has a bad sector, so we are waiting for someone from IT to copy the disk image off the internet, write it onto a fresh disk, and bring it out to us. We shouldn't be waiting very long. We hope..."
George Leaf 2
How much does it cost to upgrade the old aircraft to fancy new. Quote a certain a General to the Boeing rep bidding $21 million for the upgrade. “Every fighter pilot wants to drive a Ferrari, with Ferrari Instruments, and Ferrari Performance. This is the old farm truck. It hauls bombs. It does not need Ferrari instruments.” It works. It’s a truck, whether it hauls pallet freight or SLF.
Robert Cowling 2
The DEFCON video is very interesting. See inside the guts of a 747, see the 'avionics bay', and other areas, and a conversation on hacking planes, etc. Good stuff. Geeky stuff...

Folks, these are not floppy disks. They are called diskettes. Floppies are 8 inches in diameter and had a black stiff paper covering. These were definitely used in the 1980s and early 1990s. Earlier on we were using magnetic tape on big reels. I’m a retired IT guy and I remember it all. Those days were fun.
stardog01 5
That's correct. Always bugs me when people call the 3.5" disks "floppies." Although true floppies can also be 5.25".
Roger Thornhill 3
Open a 3-1/2" case and you will find a flexible, floppy medium.
lynx318 1
Floppy refers to the actual disc inside it's stiff or flexible sleeve, no matter the size.
paulfarrington 1
Been at it since ‘81, never called them diskettes. To feminine for me...can I have your diskette dear?
SkyAware123 -3
WRONG. The 3.5 disks are still floppy disks. HAving a hard plastic cover is just protection for the inside disk which is.... a floppy disk. Even the old 8 inch disks were called diskettes. "IT guy"
James Willich 3
We called the 3.5s diskettes because they were smaller than the 5.25s. They were all floppies, and they were all disks, but only the smallest were diskettes.

An anecdote from a few years ago. I was in a govt-taught commo class and the topic of media came up, mostly focused on magnetic media. The instructor related a story of visiting a remote commo site and asking for their recovery media. The 5-1/4" floppy disk was retrieved from its home, held, conveniently, to the side of a metal bookcase with a magnet. Had been and continued to work fine. Arguably, a workhorse, despite accepted practices.

Hehe... Surprised? Strange to me. Did you seen 286 IBM PC without 5i drive? I saw only with 3.5i, but still floppy :) Is there somethong strange that old plains use old tech?
BTW - hard copy secured more than internet, for example, you may send disks with cryptokey and data separately any way you like (taxi, post, train, etc) and it never be hacked. Even sticker with password at monitor box much more secure than internet with strongest encryption.

While it's understood and accepted that it's an 80s aircraft hence the then technology but if a simple thing of data exchange procedure has been improvised since then, offers significant advantages of time saving amongst others, it says well to upgrade.

For the same argument of 80s, haven't any other part of the same aircraft been changed, read upgraded, to a newer or more advanced kind over the years? I'm sure the answer is Yes.

Hence, my above expectation holds.

Keep in mind that until recently, the FAA systems still used equipment with vacuum tubes. "Whatever works" may apply, but at some point, it should be "Whatever to keep it working".
Terry Briggs 2
Nothing wrong with vacuum tubes. The first transatlantic telephone cable installed by AT&T in the mid 1950s used vacuum tube repeating amplifiers, even though AT&T had just successfully developed the first transistor. These amplifiers were inline with the cable and laid on the ocean floor, and were subject to adverse conditions. They wanted proven reliability, which they got.
Ron Bouknight 4
Agreed. My dad was a radar tech in WWII. He could fix anything electronic as long as it had vacuum tubes and a schematic. I can't tell you how many trips we took to the drug store to test the tubes. Hard to imagine now that the tube testing equipment and replacement tubes were available at most drug and grocery stores back then.
Terry Briggs 2
My dad was handy too and did his own TV & radio troubleshooting & repair work so his sons were familiar with vacuum tubes. I built a Knight-kit 6 band radio with him. He had his own tube tester & also alerted us to the dangers of electolytic capacitors.

The hardware and software re-certification effort and cost for something as simple as updating the boot loader and media type, is astronomical in terms of avionics equipment. If it ain't broke, don't fix it...look at it as a security feature...not everyone has access to this antiquated technology.
