I know the previous topic was locked for various reasons. But here's an official video on it. I don't know if the old topic can be reopened. Or this one gets locked too? But the video is interesting.

That narrator was s l o w……….
Playback speed at 1.5x fixes the s l o w, imo
Wow. That narrator speaks so slow. I set it to 1.25x speed and it was still a bit slow.
I believe he was pilot in command and rank didn't matter. He was the instructor and the one in charge. I'm pretty sure that's common in US Army aviation.
I've heard of transfers where a higher officer might be trained by a lower ranking instructor on new (to the student) equipment.
The pilot in command is not determined by rank.
The most important part. They tested 3 other UH-60Ls from the 12th battalion.
All 3 test choppers showed the same 80-130’ lower indicated altitude (once airborne) than actual MSL altitude. It’s quite possible the crash chopper was flying exactly the indicated altitude they were supposed to be.

Does this change anything from what was suspected early on? Is there something about the operation of a helicopter and an analog barometer that causes faulty readings?
I never relied on the barometric altimeter when flying low level - it was always RADALT. Set the bug at 80’ 9 and if it chirped, tweak the pitch just a hair. Got pretty good at telling exactly how high I was without the RADALT - but I would never have used baro.
Baro doesn't compensate for height above terrain, and baro gets wonky at very high speed. Admittedly, that latter point isn’t an issue in a rotorcraft, but the rotor downwash and pressure changes could be causing errors - I still am shocked if they followed baro thinking it was accurate.

Yes it should have been his aircraft but he suggested that she turn left, then used the word "Mam" as in acquiescing. She said yes I got it. But she didn't. She should have been on the opposite side of the river from Reagan.
