Yabbut the Peenemunde raid was a planned attack by almost 600 heavy 4-engine bombers, dropping 1,800 tons of bombs.
It's highly unlikely that one or a few misguided twin-engine bombers dropping 5-10 tons at Bletchley Park is going to do anywhere near the damage, or much at all.
1800 bombs, but the only bomb that really mattered was the one which directly or indirectly killed Thiel. The two british bombers colliding and crashing on Bletchley Park could have been a disaster of the same order of magnitude as the failure of Dunquerke evacuation.
As another example of what a single bomb could have done, Claude Eatherly, against specific orders, tried to drop his Pumpkin bomb on Tokyo Imperial Palace: imagine Hiroito killed in action and every Japanese vowing vengeance on the white devils.
