I thought the old method of dropping bombs was way easier.Just let them go a split second before the cross hairs were near target,and boom the target was hit.Now with all this calibration,air speed.it is far more difficult,but it comes close to being historically accurate.The old saying put it in a pickle barrel was a laugher!The Brits had it right,area bombing.Have a "Skeeter" mark the target,and then let her fly with as many fire bombs as you could."Bomber" Harris and reap the whirlwind was the way to go.The Americans used one aircraft to get the target set up,and all the planes in that formation dropped when the lead plane gave the word.Now days they can truly put one right through a window.
