CB, oops! I didn't see the question from Old Age Pilot up there at the top.
Point is, the Bloomberg video kind of glosses over everything that happened after NYA. But in the early 1980's New York Helicopter started up (as a 135 not 121 operation) with a lot of ex-NYA people...good people. NYH was hooked up with TWA at the time. They used (6) SA-360C Dauphins and (3) Sikorsky S-58T's. Crazy times!
Of course Pan Am just couldn't leave well enough alone and entered into a relationship with Omniflight to provide competitive service that connected NYC, JFK and EWR. It started with four 222's and eventually added two WG-30's.
Also around that time (maybe a little later) was a guy who started a NYC (Wall Street Heliport) to JFK service using a couple of A-109's. I wish I could remember the name but old age is a bitch. Helicopter pilots being helicopter pilots, one day one of the 109 guys forgot to lower the gear and...crunch! Expensive crunch. That service didn't last long either. The 109's ended up abandoned in New Jersey, where most things go to die.
I think someone even tried a scheduled service using S-76's.
I guess people will just never learn.
