One of my favorite boating moments was a few years ago when the air show was in town. Fishing solo, no other boats around, out about 8 miles when a Stealth Bomber came straight overhead, looped around, came back in so low I thought I could touch him and he tipped his wings as he flew directly over! What a sight (and sound a few seconds later)
Only thing to ever come close was having a nuclear sub porpoise 100 yds behind my boat in Long Island Sound off New London, CT.
