Narrative
The pilot reported that during flight, the fuel level in the main tanks was getting low. He attempted to transfer fuel from the tip tanks, only to discover that the transfer pumps were inoperative. Deciding to land at the closest airport, he initiated an approach.
The first landing approach was high, so he performed a go-around. The second approach was also high, but he elected to land anyway instead of risking fuel exhaustion during another go-around. The airplane touched down long and fast. It traveled off the runway, where it contacted a 12-foot deep ditch that contained 3 feet of water.
No other information was provided in the source regarding the aircraft type, registration, or occupants.
