Another pointer -- if you have the ability to screw on a filter on the

so much to filter the light, but to protect the lens. 100+ knot
slipstream can be pretty abrasive on expensive glass.

Ah, aerial photography 101. The camera should never be out in the
slipstream in the first place. You can't hold it steady.
