That was sort of my intended point... that the answer is, "A ditched plane will float for a while, depending upon how much damage you do during the ditching." We have no way of knowing how much damage was done, so therefore we have no way of knowing how long "a while" is. Attempts to introduce calculations are silly, especially when those calculations are wrong.
While channel browsing last nite I caught a segment of "Unsolved Mysteries" about the Earhart disappearance. It honed in on the 2 theories crashed in ocean and interred on Saipan with interviews of many people including Elgin Long, etc., etc., etc.,
In one segment they said that if the Electra ditched in the ocean it could float for 5 hours. Where in the #$%& did that computation come from? Anyone with knowledge of the other 2 theories have any information on how these supposedly came up with that computation?
