Floatplane door open in flight

[pdw]

Oh shoot, .. rereading there i can see where you might get some humour out of that piece (catching me off guard here).

For what it's worth though, there is around 1 hectopascal drop in pressure for every 30 ft of climb. It's a fairly large fuselage whose interior expanding air has to exit somewhere to keep neutral with the external decreasing pressure with height, esp if climb is steeper (or interior pressure gradient to outside air spikes for some other reason). A four foot door in that case can place a lot of pressure on its latch, and thus expose any defect sooner.

I have had a few doors pop open on beavers before. I had a drunken American standing between the rear doors on an Otter in turbulence while he rummaged through the baggage trying to get another beer out. I had to restrain myself from stomping on the rudder that day...

there have been several people lost with doors popping open over the years-to my knowledge no survivors unless you count the beach 99 captain who hung on.

Usually they were not seated with their belts on. I can think of a few that were purposeful too..
