Try the Bielefeld Viaduct. 30yds.
The Saumur tunnel. In the hole - front AND top.
Dortmund Ems canal - bingo!
The Brest U-boat pens. One Grand Slam right in the middle, might not have been on a sixpence but half a crown might be fair.
But.........the bomb sight was an absolute beauty and they bombed from 20,000 feet, which gave the Grand Slam its optimum effectiveness.
All breathtaking really. It would be true to say that our star bomb aimers were the creme a la creme.
