The Military Times states they were members of the US Military, one USAF pilot and the other US Navy. They were performing a check ride required before an aircraft can be turned over to a foreign buyer.

Cycles because blade cycles in reaction to force vector of thrust so there is a major bending load at full thrust that does not vary with each revolution. The bending stress is reduced to a lower level at climb thrust. In this case they throttled up creating a new stress cycle and BAM. 1175 was really odd because no change in stress - cruise. Their CNN expert says the fan blades are subject to so much heat. Odd, because heat is introduced in the combuster. The fan is always at air temperature because its air cooled - range from +50C to -65C.

Interesting reading history of the plane. Purchased by PanAm in 1979. In 1980 I flew a PanAm SP Sydney to Los Angeles. Back in those days I was a very nervous flier and the fewer times the plane touched the ground the greater my chance of living (I am completely opposite now). This PanAm flight was twice weekly so I arranged my schedule around the flight avoiding a Hawaii stopover. To think the same plane may still be flying - or crunched permanently in 1980. Memories.

This is not surprising since Dupont issued a bulletin in March saying not to use this product in aviation fuel based on at least 2 incidents with loss of fuel flow to both engines. Uncertain as to why a special notice on the 737MAX except since none were flying, they may have been missed when the bulletins were originally issued.

Could the engine even start with a person there as he would be right against the fan? Could the high pressure compressor still get enough air to start with the fan jammed by the person's body? This is assuming he was missed during pre-flight.

First Embraer took Boeing to arbitration, and now Boeing has taken Embraer to arbitration. The report states that so far nothing is known of the reason for Boeing's case except they filed.

Not sure why this is newsworthy. Travel vouchers meaning the money will still stay with United, a liability like my gazillion frequent flier miles. How much would it have cost United for advertising by getting a story published?

Why is this feed even here as the picture heading the article is from President Bush's 2004 visit?

Transonic region from mach 0.75 to mach 1.2, design affected by area rule in that shock waves are reduced by constant area cross section. Wings increase the cross section. The increased upper deck length of the 747-300/400 had the effect of making use of the area rule to gain high mach possibility with reduced drag. Convair 990 has pieces added to take advantage making it the fastest commercial airliner to date. A380 has configuration at wing root to take advantage. I understand it was by chance, not design, that the 747 was able to take advantage another reason the -400 is faster and uses less fuel than the -200. Now don't ask me why the short upper deck on the -8F.

First thing I thought of when I read the headline. How could they not account for spills. Spill proof cups and everything, I still end up with spilled liquid due to unexpected turbulence - on the ground. Don't pilots have other accidents too like maybe getting sick during a long flight? Surely they - wait, illness from having eaten the fish, of course, and don't call me Shirley!
