Barnstormer,
The issue over mixed crews with different -53s is always raised as a reason for failure - imagine trying to get a mixed bag of UK Merlin Mk1/2 & Mk3/3A drivers with competing RTS, crew training and SOPs to mount something similar.
Wiley,
I defer to your experience, but would say that a lack of "Mission Command" delegated by senior officers/politicians is nothing new (just think Rolling Thunder...) and that a victory has many parents and a failure has an alarming lack of them...
