Well, could this technology be used to augment the performance of
canards? We know that aerobody designs that are optimized for
high-speed supersonic flight may unfortunately not be so efficient for
low-speed flight around takeoff and landing. Could this sonic lift
technology be used instead of canards, or maybe to boost the lift from
canards? Then maybe you could have smaller canards at least, although
I'm not sure liability canards pose to begin with. Also I don't know
what you'd do in the event of an unpowered landing.

I was also thinking about how stubby-winged re-entry vehicles like the
old X-15 or even the new SpaceshipOne might benefit from that 20%
increased lift.

What about using this technology for something more exotic, like a
martian aeroplane? With the thinner atmosphere producing less lift,
perhaps this sonic boost might make a crucial difference.
