Definately a Lanc in the sand. Maybe others.
In the 60's I did about 50hrs flying with No 1 AEF based at Manston. There were a couple of VR pilots who seemed to know more about this Lancaster than others and when ever it was exposed a low level flight was always taken for just another look. I saw it many times. However you did require a very low tide and one of the many sand shifts to be in your favour.
