Tight Fit
Two of the three Lockheed Martin RQ-3A DarkStar unmanned aerial vehicles built are shown packed in a C-5B Galaxy on their final flight from Palmdale, California, to the US Air Force Museum at Wright-Patterson AFB, Ohio, in December 1999. DarkStar first flew on 29 March 1996, but it crashed during its second flight a month later. The second DarkStar (shown at left) was modified to increase its stability and first flew on 29 June 1998. It is now on display at the museum at Wright-Patterson. Two additional DarkStar vehicles (including the one on the right) were completed, but they never flew. One of those aircraft is on display at the National Air and Space Museum in Washington, DC, and the other is on display at the Museum of Flight in Seattle, Washington. In January 1999, the Department of Defense terminated the DarkStar UAV program because of budget cuts. The C-5 that carried the DarkStars was based at Travis AFB, California.

It was basically a PIO issue. The flight control computers got out of phase with the airplane dynamics....with predictable results.I was at the B-2 CTF that day it crashed. From what I understand, Boeing had the flight control software and there was no way to reject the takeoff, there were issues right from the git-go during the takeoff roll. We could smell the burning composite from South Base, got a nickname, Falling Star (one of the nicknames anyway). It was some time ago and anyone please correct me if I'm wrong.
How does that happen with computers?!?It was basically a PIO issue. The flight control computers got out of phase with the airplane dynamics....with predictable results.

It’s still a pilot induced oscillation, although many would say that is harsh as it imples blame.How does that happen with computers?!?
Did this come from the SDASM or somewhere else?AV-1 RAD event April 22,1996 screenshots
I remember this one cranked kite concept that has appeared two times in AWST (2001 and 2003) long before SensorCraft development timeline was published, both times referred as 'one of Air Force concepts studied'. Note that both LM and NG have cranked kites HALE concepts studied and I guess LM flying wing SC have roots in AARS/Quartz
Can someone point out the genesis of this carpenters square design? I'd like to get an idea of where/how it started being used.

I always liked Pilot-in-the-Loop Induced Oscillation, which came up around the time of the YF-22 and Gripen incidents, but never really caught on. It better captures the pilot as only one element of the issue.It’s still a pilot induced oscillation, although many would say that is harsh as it imples blame.
