Reference the overweight landing. Of course, the Vulcan had no fuel-dumping system. After getting airborne with a gear retraction problem we had to burn down to landing weight. We had the gear down of course. The airbrakes were put out and the bomb-bay doors opened. It still took several climbs and descents to 20,000 or thereabouts to burn off enough fuel. Goodness knows what the fuel burn was in the climb.
