Today, two other RVs plus mine took off from Essex Skypark and headed over to Millville Airport, New Jersey for a delicious lunch at Verna's Flight Deck Diner. On the way back, crossing the Delaware Bay at 5000 feet or so, I saw a C-5 Galaxy about two thousand feet below. It isn't often that I've looked down on a big jet! He turned west, as I was, and pulled away. But then he turned north followed by a U-turn heading south into Dover Air Force Base. I turned north so we were on opposing courses and I watched him pass by me, 2,000 feet below. This time I had my camera ready!
