What is Helo Dunker?
Helo Dunker meaning Dreaded training device that all naval aircrew and pilots must endure every few years when they complete water survival training, or ‘swims.’ Designed to simulate crashing a helo at sea, it is basically a huge metal drum with seats and windows that is lowered into a pool and then flipped upside down with the ‘passengers’ strapped into it.
