“Contrary to popular belief, it actually was and is possible to hit military aircraft installations. “
You must get your ideas of what was possible from Hollywood.
‘Precision bombing’ in WWII parlance meant that you hit somewhere close to what you were aiming for.
In theory the top secret Norden bombsight was capable of delivering a bomb to within 75 feet of the target. In actual practice bomb accuracy was only within 1,200 feet of the target. And not every plane was equipped with a Norden sight.
When Naval aircraft attempted to hit a ship they would employ dive bombing or skip bombing and a lot of hope. The Air Force relied on the Norden sight and a whole lot of planes.
If you can wait for good weather (in such a siege the enemy is going nowhere, and no help is on the way for them, so you can wait till the cows come home), and you have no opposing aircraft (cuz 5,000 P51s have swept them from the sky), and there is no AA fire coming from the ground (cuz every time something pops you bomb it until it’s dead)...
then you have a “milk run”. You come in straight and level at 1,000 to 1,500 feet, drop precisely where and when you want.
Bomb accuracy within 1,200 feet from the target is not the case in those conditions.
I’ve said this in every post I think - AIR SUPREMECY FIRST.
Which is what we had at war’s end.
Then bombing accuracy is no problem.
