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.

Many WWII fighter aircraft reached speeds in excess of 400 MPH. The problems didn't occur at those speeds but at the speeds obtained during dives, in which the planes approached the speed of sound. The P38 was especially prone to having the controls lock up during high speed dives.

High aspect ratio wings are no problem these days with CNC molded wings of carbon and kevlar. Still, I have seen more than one video of a ship simply exploding in mid-air from flutter. Extremely tight linkages with no slop are a must.

Do a little research on the subject. You will have to take up your argument with the PhD's in aerodynamics if you still have doubts. Here are a couple of links to get you started.
