Nifty.

Your points.

1. The RAF did order a "large and expensive fleet (300 aircraft) of Vengeance bombers in 1940". The British taxpayer paid for them and took delivery in 1942/43. They would therefore have been available, manned by trained crews, bombed and fuelled up, and ready to blitz Hillman on D-Day and support 21 Army Group through to Bremen in April 1945 if the RAF had believed in them. I have no idea, therefore, what you are talking about or what point you are trying to make with your sarcasm about resources being limited.
2. Of course aircraft vulnerable to FLAK were used in the FLAK suppression role. How else could FLAK be suppressed in WWII, or in Vietnam come to that?
3. I told you I was considering further the use of aircraft against fixed defences. The Wiki article I quoted claimed the German hollow-charge bomb could penetrate 11.5 feet of reinforced concrete. Hollow-charge bombs would have been developed by 1943 in order to rectify the Stuka's problem with the fixed defences in France/Belgium and at Sevastopol.
4. Airborne PAKs could easily penetrate the StuG III's 12-mm top plate and the 10-mm top plate of the Jagdpanzer IV. Rudel in his Ju-87G2 aimed his twin 37-mm guns at the engine covers when destroying 519 tanks and 150 StuGs. BTW, you know Rudel's withering opinion of RPs as "Quatsch". He told some Typhoon aces of 2TAF that he had tested RPs and rejected them as too inaccurate compared with guns. He did his homework while 2TAF did not.
