Hi. An ignorant civilian here with a question. I've never been in or
near a helicopter.

The May 2010 USNI Proceedings (pg. 78) mentions that "[t]he Navy's
H-72A's have several specific equipment additions, including
jettisonable cockpit doors...." I can understand jet fighters have
jettisonable cockpit canopies but I'm having trouble imagining
circumstances in which a helicopter would need to have jettisonable
cockpit doors. Can someone please clue me in?
