I'd like to see a little bigger blast area. Especially higher up off the ground.
A 4000 lb bomb dropped in the middle of london would have cleared off a
A: Area the size of a city block?
B Cored the center out of 4 city blocks?
Look at the devestation caused by the V2 rockets, & they only had a 2k payload!
A single 4k bomb in AH should pretty much level the town. Perhaps missing the farm & 1 or 2 other buildings.
In short make the bomb blast bigger. Not on the ground, but higher up.
