The massive Flak tower in the Berlin Zoo park was in The British occupation zone and it took them over ten years of work before they managed to demolish it all. The remains of the tower which Rene visited, is in the old French occupation zone of Berlin . The French tried to blow the tower up with explosives three times .

I think the Americans were not keen on daylight bombing of Berlin because of the projected losses , they had just suffered heavy losses with raids on other German targets and they were in a rebuilding phase.
