i am interested in unmanned aerial vehicle and I want to realize a project about this topic. For this reason, does anyone can suggest me comprehensive source to follow development on this topic?

 

See your local remote control club!!
Or is this a dirigible, Ala count Zeppelin?
Max.

 

If only there was some way of searching the World Wide Web for such information...

Interesting how we used to develop secret spy planes more or less in secret.

 

There were always leaks in the aviation press. Some of them were intentional to confuse the Soviets. The time schedule for the development of the SR-72 makes keeping secrets increasingly difficult. To test a Mach 6 aircraft will require more than a few area 51's

Sure. The very name F-117 was a double misdirection. It should properly have been called an 'A' since it is an attack aircraft and the '117' made it appear to be an old project affiliated with the 'century series' fighters.

Oh, I don't know. There's LOTS of empty ocean space around. And Boeing has test flown Mach 5+ aircraft without a lot of fanfare (though not without a lot of secrecy, either, but I suspect they could have easily done it under the sheets if they had been so inclined).

Arguably the political climate today is so different than the Cold War era that the peceived need for secret capabilities isn't nearly as high as it was then. Thus, the political payoff for announcing these kinds of things win out. Note that I'm not necessarily objecting -- I like knowing about this stuff just as much as the next nerd -- just that it's an interesting observation point.

Not really planned, but the SR of the SR-71 was originally RS for Reconnaissance/Surveillance. Lyndon Johnson got it backwards in a speech and the name was changed to match his mistake.

 

I've heard it claimed that the name was actually changed by LeMay prior to Johnson's speech and that the speech, as written, actually reflected LeMay's change. I don't know what the actual story is.
