Thought I remembered reading something on this subject elsewhere, then found it here:

The pertinent part comes in the airframe description of the Mi28 Havoc:
"port-side door, aft of wing, provides access to avionics compartment large enough to permit combat rescue of two or three persons on ground, although it lacks windows, heating and ventilation."
I've a feeling the Israelis also took a hard look at mods to their AH64s with a view to using them for battlefield extractions too.
