Cluster f**k!
2 helicopters in close proximity and blind to each other.
Relying on the one crewmen for separation!
Old trick - when in close proximity to each the guy in the blind spot shall keep the other aircraft visible and it is up to him to get out of the way. It works.
Agree on the recovery of the fast rope - it should stay with the team.
The kick it sideways to slow down in a 117? I hope you have plenty of T/R parts.
