I'm a volunteer photographer at the American Airpower Museum. The web site is improving (I know, I know) but if you are on Facebook, they keep their page there pretty up to date. You just missed a huge weekend at the museum - we host most of the aircraft that participate in the Memorial Day weekend show at Jones Beach (Yes, Fifi was here). Over the summer, we send some of our war birds off to other shows, but for Labor Day weekend at the beginning of September we usually have a big event - last year we had the Canadian Lancaster, as well as a Spitfire on hand to mark the 70th Anniversary of the Battle of Britain. Other times during the summer, it's a question of weather and pilot availability as to whether you will see anything fly, but there is also plenty to see in the museum itself (the museum is housed in a hangar where P-47s were built during WWII). If you have any questions about the museum, or are planning to visit, drop me a line!
sees a ton of corporate aviation, not much airline traffic. JFK
are your best bets for spotting heavy iron in the area. Local law enforcement around EWR
strongly discourages aviation photography. Again, I'd be glad to answer any specific questions you might have.
