- toomuchtodo 12y agoThey are! And they work well at both subsonic and supersonic speeds, just not transonic speeds.
- anovikov 12y agoNo, these things are just for improvement of stability when descending. But it seems that answer is aerodynamic control by partially (and differentially) extending the LEGS. Which appears brilliantly smart and should work. Same hardware, zero additional weight or cost, additional function.
