The ejection seat does exist for helicopters. And how is this sad? Let's see how you feel when a guided missile is flying towards you at 700 miles per hour.
Ummm, I think that kinda might be incorrect: For improved pilot survivability the Ka-50 is fitted with a NPP Zvezda (transl. Star) K-37-800 ejection seat, which is a rare feature for a helicopter. Before the rocket in the ejection seat deploys, the rotor blades are blown away by explosive charges in the rotor disc and the canopy is jettisoned. http://en.wikipedia.org/wiki/Kamov_Ka-50
