There is also a nice museum there :
Cradle of Aviation Museum, Garden City, Long Island, NY
The last aviation companies on Long Island were Grumman ( F-14 ) and Fairchild ( A-10 ). Fairchild also had a short lasting partnership with SAAB on the SF340 turboprop. The jet trainer contender never made it in the competition.
I got a job offer from Grumman back in 1979, but it was clear that Grumman Beth Page was a dying place for aviation.
Like many military aviation companies, most on the east and west coasts were consolidated or killed off ( due to lack of contracts ) .
