Some 40 years ago, during my electrical apprenticeship I had a second job as manager of a roller skating rink. The primary owner was an experienced pilot, both fixed wing and helicopter. He wanted to get some time in, and rented a Cessna 172. There was a tiny airport near the rink called Flushing Airport that had a tiny sliver of a corridor through a very busy TCA. Went for a ride up to Middletown (Orange County) and back. Having all that LaGuardia traffic around us coming back in was to say the least "disconcerting"
