If you are wearing flying boots, ring of levitation, or have water walking (boots, eurynome), and you attempt to use the travel command to cross Dagon's swamp, it's possible to drown.
It appears that the travel command sees the flying boots and charts a path that moves through water, but doesn't realize you can't fly/walk/levitate over the water in this swamp. The travel command will not abort once you enter the water, and you can drown if you run out of breath with no land squares nearby.
The travel command works fine if you have, say, speed boots equipped, as the game will not chart a path that goes over water.
