"Arresting is certainly a good option - we've been doing it for decades, see here;  F4 arresting F18 arresting And our early RPV in early 90s (not arrested! 65 lbs): RPV"

Tj Bordelon replied to Andrew Rabbitt's discussion DCM - how is the order of rotation chosen?
"This is not true. There is a specific order these rotations are applied. In aero, it's usually yaw, pitch, then roll in that order. And this is true ONLY if you are going from air to ground coordinates. It's reversed for the other…"

Tj Bordelon replied to Juan Carlos Hdez's discussion sensors in the arms?
"I wouldn't discount the idea. I had my IMU in a wingtip and the accelerometers worked. I bet as accels get lower in noise, you may start to get useful rotation data-- where one wingtip accelerates up and the other down. I think the idea is…"

"Ok, I get it. Both of us agree that "this is the way it is", but you go along with it in principal while I don't.  We also disagree on whether or not the govt has the "right" to do what they do. Fair enough."

FreeSpace Autopilot Crash!

Posted on October 18, 2010 at 6:30am 26 Comments



I rarely crash. Maybe I've been lucky? I had been ignoring a bug for the longest time only to have it occur just as I was over the trees ready to land. There was no time to recover.




Toward the end of the video you can see the crash. The plane is trying to follow a runway beam but winds up oscillating back and forth and eventually tip stalls. The only thing that saved me from ending up on the roof of the barn was accidentally…

Successful reverse thrust landing in 28+ mph gusty wind

Posted on October 9, 2010 at 7:50pm 14 Comments



Ever fly on days you know you shouldn't? Trees were swaying, and my gut was saying no. But I guess you never know until you try. I'd have to say that I couldn't fly in this wind. The ground track of the aircraft was so unintuitive, especially on landing. At times it was just hoovering overhead making minimal progress.



Days like this that really test your autopilot.



Anyway, this video shows my full auto-landing sequence, complete with the dive from 180… Continue

Sounds great, but aren't you the same TJ Bordlon who worked for NASA and has sent balloons to the edge of space?
