Crashed or dumped?

Stunning pictures reveal hundreds of World War Two aircraft lost for over 70 YEARS on Pacific Ocean seabed

The article implies that the 150 planes were found “crashed” in the same area. That may be an error, I suspect they were likely dumped as unserviceable during the war or as surplus afterwards given they are all American makes of disparate types.  Cool pics though.
