About Long Island, "Cradle of Aviation"

Google Earth Community: Mock Aircraft Carrier

There's also 60' x 60' cross in the former practice circuit for WWII on Long Island. This might have gone with the mock destroyer and mock aircraft carrier outlined with white rocks in the pine barrens so far identified by Mitragorz. The USGS old topo map in NASA's World Wind shows the cleared flight "lane" well. (There's a small white cross in Camp Hero too though about 15' x 15' probably for aerial mapping out in Montauk, NY.)
