a few minutes of googling told me that both the Ka-50 and the Mi-28 are equipped with ejection seats, but they haven't been used in earnest. What I've learnt is...
...in the case of the Ka-50, an explosive charge detaches the rotor from the helicopter, and then the ejection seat fires upwards.

The Mi-28 is equipped with ejection seats that fire to the side and downwards.

My questions are:
- why didn't the western countries bother to develop an ejection seat for helicopters?
- in the case of the Ka-50, is the whole rotor separated from the aircraft, or only the rotor blades?
Any information on this strange topic is appreciated!
