Ok, our brill-yunt popular press said something about 15K which, I THINK, on average means generally functional, but with impaired judgement...
If you mean Flying mag, it HAD it as 15K, then ammended it to 19K,
Plus, F-16s intercepted the plane and reported that "the only person on board the Cirrus was unresponsive likely due to hypoxia."

It would be very interesting (but unlikely) if they find the plane to see if there was some issue with the built-in O2 system that this plane has.
PS: No comments on the streamer YouTubes? You've seen all that years ago and never shared? I've seen a plenty of smoke-trail ones, but the smoke streams really mix up and go away just past the leading edges, unlike the streamers.
AND, I found the secondary stall and spin, from a MEASURED, but G-loaded pull up was impressive and educational...
That was a nice video. I had seen not those but OTHER videos of streamers put in wings of planes, some of them of "official" test flight (including airliners and small GA planes), and some (very interesting) of simple pilots that did it for their own leaning and sharing. And of course, I had seen that stuff myself in wind tunnels in the University.
The one of the F-70 was very interesting. According to some comments in YouTube from people that understand the language being spoken in the plane, they had to activate some sort of stall-recovery rockets that they installed in the tail for the test flights. I would really like to know the full story behind that one. Remember the Fokker is a T-tail and the title of the video says "deep stall". Did they manage to put the plane in a situation that would be unrecoverable without the rockets? Did they pull the CB (or overrode) the stick-pusher?
