There have been numerous instances where A-4's have landed on the drop tanks after experiencing unsafe gear down problems. It was a NATOPS procedure; part of the Landing Gear Emergency Extension procedure. Saw it happen at NQI once. Plane was back flying the next day after the malfunctioning nose gear part was replaced and the drop tanks were replaced.
That's a pretty ballsy move, one I wouldn't want to have to execute. I can't imagine watching that go down, and then seeing it fly the next day. A testament to the design of the airplane.
