Wanna see something even faster without spending $4K on a turbine jet? Check out “dynamic soaring”, a phenomenon in which a glider uses the differential in wind speed between the windward and leeward sides of a ridge to accelerate to phenomenal speeds. Over the last few years pilots have kept increasing the speed and they are now approaching 500 mph. Check out this and other videos on YouTube.

I built and flew quite a few gliders - many flown in Gorman, Ca hills at speeds of 250-300 mph most days. Only one thing about that - a lot of the earlier ones simply 'blew up' - traveling faster than the build would tolerate. It took a long time to design one that would hold together at such speeds.

But, I had the most fun with a big slower craft that carried a camera to take pictures of the falcons, eagles and condors that often came up to fly playfully alongside.

I’ll be polite, and not simply call “BS”. However, I do have two basic questions for the actual aerodynamicists in the group. First, how does an aircraft with straight high aspect wings survive those speeds? Isn’t this in the realm at which WWII fighters began to have structural and aerodynamic failures? Second - a hand-held radar gun that accurately measures 460+ MPH? Really?

I would appreciate some concrete references, rather than expend all of my credibility points.
