Interesting story here:
The link to CRUSADER is of not obvious, but it is through the pilot of the Mustang of No. 2 Squadron R.A.F. which did the low-level recce at 1,000 feet, Air Commodore Geddes. As a Wing Commander in 1941, he was an observer in the RAF Command in North Africa, tasked with observing and analysing Army Air Co-operation. He wrote a pretty scathing report on the performance of the RAF in this regard.
