We have a family friend who was a young sailor on a Canadian warship in the assault fleet. He had a front row seat to the invasion. IIRC they spent part of the morning plucking GIs out of the water down in the American sector.
His D-Day story is picking up a foul-mouthed US pilot that dropped below the clouds to get a bearing. The invasion fleet opened up, and downed him.
Berra was surprised the pilot survived the fusillade.
