Air superiority would have to be gained before an invasion would be possible.
P base models were similar to these Apache aircraft and were also utilized in the low-level ground attack role, though these were built with 4 x 20mm Hispano-Suiza long-barrel cannons instead of machine guns and underwing bomb shackles for bombs.
Visibility out of the "razorback", framed cockpit was noted as inadequate for the rigors of dogfighting.
The tide of the air war in Europe had officially shifted and the end of Germany's Third Reich was now in sight. Though fewer in number, the P could penetrate deeper into German airspace than the other U. Thankfully, the aircraft still exists as a prize for aviation collectors and remains a favorite at airshows across the globe.
Fortunately the British decided to gamble on this seemingly risky proposition. The flap control lever was activated from a low-set position within easy reach.
A reconnaissance version of this model existed in the F-6K. The KA beginning with the D-models dominated a good portion of the top forward viewing with its noticeable "No Hand Hold" message staring back at the pilot. There were P and P fighters available in England to supply protection, but they did not have the range to cover all the desired targets in Europe.
There was no safe place where German aircraft could fly without being attacked. The arrival of the PB could not have come at a better time. Like other World War 2-era airframes, the now "F" Mustang was thrown into the combat mix and would see action in the early and middle years of the conflict until replaced in quantity by more capable jet-powered types.
