A bit more background material: I attended a lecture given by Captain Haynes at the Smithsonian's National Air and Space Museum after the museum regular hours were over. This was about a year after the accident. The Langley Imax Theater was packed with aviation geeks and no small number of pilots. They played the whole radio traffic exchange and then that video of the plane doing cartwheels down the runway. Then they introduced Captain Haynes.
Everyone in the auditorium stood up and applauded, giving him a five minute standing ovation. This was no ordinary audience. These were his peers in the aviation community. Note that just across the street is the FAA headquarters. I have little doubt that there were more than a few FAA people there too. And we all applauded.
This failure was later recreated with multiple crews in a flight simulator. Only a small fraction got anywhere near the airport, and only a couple actually made it anywhere near the runway. This was literally a command performance that has not been replicated since.
Those hydraulic fuses that they installed in the MD-11 to prevent total loss of hydraulic fluid, are officially called "Haynes fuses" in his honor. It was a terrible accident, but it also turned out to happen at the very best time. Only a week before, the Iowa National Guard had practiced for a large aircraft crash at that airport.
The time was also fortuitous because hospitals in the region were approaching a shift change, so they held everyone there in preparation for the influx of casualties. The national guard was completely ready and practiced for this event. If it had to happen, they couldn't have chosen a better place. There were many heroes that day. Let us all be thankful they were there.
