The unhanded engines and the lack of the turbos were both
serious errors.



Perhaps but the fact remains that the aircraft as delivered did not
meet the manufacturers claimed performance specification.

The second batch of aircraft (Lightning II) would have included
the turbos, one of the reasons they were omitted from the first
batch was reportedly that there was considered to be a serious
risk of delay due to shortage of turbochargers.

Its also worth recalling that the RAF accepted into service
other aircraft using un-turbocharged Allison engines. They
were rather happy with the Kittyhawks and Mustang I
despite their altitude limitations.
