Hello Tony H,
KNO = Killed, None Operational.
could mean that he was in a ground accident, or as a result of bombing, or ferry flight etc etc.
RTD = Returned to Unit.
As for "exact" date of departure of the 55FS from Wittering to Kings Cliffe? I have put my references back on the shelf.
But from Wikipedia -
see here at
http://en.wikipedia.org/wiki/RAF_Kings_Cliffe.
The 55th FS was brought to Wittering as there was not room for it at Kings Cliffe initially.
Transfereing from Kings Cliffe to Horsham St. Faith on 6th April 1943.
And from Wikipedia 20th Fighter Group page -
HMS
Queen Elizabeth dropped anchor on 25 August and the men of the 20th disembarked at the
Firth of Clyde. From there they were transported to the docks at
Greenock, Scotland, and then, by train, to their new home,
RAF Kings Cliffe, England.
Fortune smiled on the 55th FS at this time. Due to space restrictions it had to be stationed at
RAF Wittering, about five miles from the rest of the group. The facilities at there were much superior to those at King’s Cliffe. The 55th Squadron joined the rest of the group at King’s Cliffe in April 1944.
