Another story was that an F4U was used to spray for mosquitoes after the war, probably using the rig developed to lay down screening smoke, a prewar tactic to preclude accurate targeting of warships like Langley here.

The best time to spray for mosquitoes was thought to be first thing in the morning when there was no wind. The best altitude, according to the story, was as low as possible. You can imagine what a bored fighter pilot (or wannabe fighter pilot) would do with that.
It turns out that both stories have a basis in fact, passed down orally by station personnel for ten years in this instance. By chance Dana Bell sent me a report of an F4U crash, with pictures, that had occurred on Sangley Point in July 1946. The pilot had been up early that morning spraying DDT for mosquito control.
When he went to lower his wheels for landing, the right main gear and tail wheel extended but the left main gear trailed. He then noted that his hydraulic pressure was low. He cycled the gear a few times with the same result. He then tried pumping the gear down and hard pullups. In the end, after raising the gear one last time, he attempted to extend it with the CO2 backup. Again, only the right main and tail wheel extended. And now there was no longer any hydraulic pressure so he couldn't raise the gear for a belly landing. Given the choice of bailing out or landing with one wheel extended and the other trailing, he opted to stay dry.
He wound up against the sea wall at the west end of the field.
This is a picture of Naval Station Sangley Point in 1965 (it couldn't be a Naval Air Station after Cubi Point was commissioned in accordance with a treaty with the Philippine Islands that limited the U.S. to one NAS in the Philippines). You'll note that it wasn't much more than a very big but immobile aircraft carrier. (It was a seaplane base before World War II; the runway was added after the Philippines were retaken in 1945.)
