Regarding the Hampden in Rotterdam it's almost certainly P4324 code QR-P of 61 Sqn, which force landed on the island of Vlieland in the Netherlands on 27th August 1940 after running out of fuel. There is no damage to the props which suggests it has not been raised up after a belly landing.
No doubt it landed on the beach in this link!
