it would be pretty dam easy to stick a couple of 100 buck epirbs (as compulsory on all boats that go more than a km offshore)at the outer edges of the wing tips into every plane...even if the plane crashed its unlikely the epirbs would be destroyed

Easily locatable to a few metres.

daft how they dont already have them.
