In Flight Malfunctions and Emergencies

Removing the co-pilot controls requires an A&P, and theres frequently
not one available when you need one to do it.

If Bob-Volpe is around who used to work for Island in NYC this brings up a
question.
As busy as Island was back in the 70s/80s
especially with sightseeing flights, did they have a mechanic ON DUTY at the
East 34st Heliport in case something happened or would they have to fly one in
from Garden City where their hangar was which I believe is about 15/20 flight
time.
Thanks.
