Great algorithms for the formation flight. We actually worked on vehicles like those the size of a bumble-bee, even using the bumble-bee wing rotation motion.

Some great strides being made in miniaturization.

Sandia National Lab recently developed a precision guided round for the .50 caliber machine gun and sniper round. Has to take quite a few "g"s as it accelerates from 0 to 3000+ fps (~mach 3, SR-71 speed) in about two feet.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

That would have been something in my time in the Army....Don't know much about flying (I used to jump out of aircrafts for a living) but sure as hell know about bullits...would have made life a whole lot easier!

ever wonder how movies like terminator can predict these things with such accuracy decades before we hear about them? Freaky.

Jeroen- I know quite a bit about flying and can happily say I have the same number of take-offs and landings. I have few friends who cannot say that, and all of them are at least an inch shorter than before they ejected from their F-111.

Is that a black out situation? Seems like that would be alot of g forces at work. And congrats on the takeoff to landing ration, well done.

LOL...I know a few like the guys you mean...we thought they were so crazy we couldn't wait opening the door (at any altitude...) to get the hell out of there, day or night...
I think a congratulations to you is in order, Sir. In the Dutch Airforce the same number of take-offs as landings was worth quite a lot of booze at the end of a career.
Makes me think of a very good friend of mine who is about to get his last promotion (he's a Colonel in the Air Force and will be General somewhere soon). He used to command a bunch of Patriot missile units and one of them accidentally fired one whilst stationed in Israel during the Golf War. His ass was all over the news...didn't even get fired?! To me the Airforce guys have always been too trigger happy, be it on the ground or in the Air. no offense...
I've been on the ground many times showing them where to drop their fireworks praying they wouldn't have an off day...

55 seconds in, what appears to be 3D cams along the walls. Possible that the entire control system incl positioning is not on-board the coptors, but is based on a large, motion capture system?

What do you think Taz?

BG,
