VIDEO: Southwest Airlines 737 Nose Gear Collapse at Pushback
On August 4, 2016 at 9:02pm eastern daylight time, Southwest Airlines flight 149, a Boeing 737, N368SW, experienced a failure of its nose landing gear during pushback from the gate at the Baltimore/Washington Thurgood Marshall International Airport (BWI), Baltimore, Maryland. The aircraft was substantially damaged and there were no injuries to the 6 crewmembers or 129 passengers aboard. The flight was being operated under 14 Code of Federal Regulation Part 121 as a regularly scheduled passenger… (www.youtube.com) さらに...

That tug driver was going about as fast as the SWA guys when taxiing around at MDW (i.e., approaching rotation speed). LOL
The brakes on the tug came on twice before the collapse, and the aircraft was moving at a high speed. Given the mass of of the loaded aircraft and a sudden tug (no pun intended) on the nose gear, it seems to have just folded. The tug driver's statement indicates that he struggled to bring the speed under control, and you can see the tug and aircraft jerk on the second application of the brakes.
How much force is the nose gear expected to handle in that direction? During deceleration and braking after a landing, the forces on the nose gear are in the extending direction -- during this incident the force acted in the opposite (retracting) direction.

Agreed.
Roy and Bart, At the point in the video when it happens it looks like the jet roll a bit to the left suggesting a MLG collapse. Checkout the video at about the :47 seconds point and beyond, you can it was in fact the NG that collapsed.
Question to Tug driver "Wanna get away?" In 1967, I was aboard a Navy P2 Neptune ASW aircraft that stopped to pick me at Wheelus AB. It had pulled into a wash bay but when it was time to leave. there was no suitable tug to push back. Also the plane blew a seal in the nose gear which the crew chief repaired well enough for one take off and one landing. The pilots used the prop engines in reverse prop mode to back us out. Interesting at the time.
Looks more like main landing gear
