Would an aluminum shield, or screen above the antenna disperse the interference, or is the whole signal scarmbled and that's it?
If the shield, like aluminum foil on cardboard or a metal screen, is above the antenna so that the antenna doesn't "see" the aircraft above, but does see the TV signal, it might help.

A 4-bay antenna would be better than a Yagi, because it has a narrower vertical beamwidth:





It is possible to restrict the acceptance angle of an antenna even more by putting it in an enclosure:

I'll get it turned to the south and maybe the planes overhead won't interfere.
That's a good idea to try. Where we were living before, the antenna faced a road with heavy traffic. The cars going by in front of the antenna only affected the weaker signals.
