Dunno how to phrase it well, but “foreign military helicopter crashes on military base/school’s lawn as part of an attack on a high value target just down the street” has got to suck for someone. Kinda like a karate black belt getting mugged, and his date looking at him going “WTF?”
Don't fret. The dust kicked up by having multi helicopters in a small space leads to this type of mechanical difficulty. Setting it down and getting everyone relocated and then securing it is, in itself a part of this successful mission.
