You have that right. The flying wing had lots of problems with stabilization.
OTH, the engineers thought they could “power through” the problem. To whit, the more power we apply, the more we can overcome the problem.
Trouble is, it didn’t work out that way.
The B-1 and B-2 fly the way they do because of computer control.
The Horton didn’t have that advantage. Ahead of its time? Ohh Yea.
But like the magnetic tape recorder, invented in 1920’s, it needed peripheral technology to catch up with it to make it work.
Initially, the tape recorder used PAPER tape with magnetic paste to make it work. It did, but the freakin paper kept breaking. The project was put on the shelf until PLASTIC tape came along and stopped the breaking tape problem.
PS: The damned NAZIs were the first to figure that out.
You might get a kick out this if you haven’t seen it before.
