A friend of mine, who unfortunately passed away a few years ago, was in the Luftwaffe during WW2. He told me he was part of a special unit, based in Normandy, that was suposed to try new equipments. One of them was a 88mm gun mounted on a He 111, the were sent over Great Britain to destroy the AA baloons that were making low altitude bombing impossible. He even told me about the way they could aim the gun and about some copper ring partly covered with rubber that would help keeping the gun from firing in the wrong direction as it was rotating and electrically fired.
has anyone heard of this unit ? and has anyone heard of this modified He111 ?
