David ! .... how come you kicked off with a hard one ??

Don't yell at me 'cos I'm learning ..

but I found this about 97 squadron ... does this help ??
97 Squadron went through three incarnations during the Second World War, of which only the third saw active service.
At the start of the war the squadron was a training squadron in No. 6 Group, operating a mix of Avro Ansons and Armstrong Whitworth Whitley. In April 1940 the squadron was redesignated as No. 10 Operational Training Unit.
The second incarnation was very short lived, lasting from 1-20 May 1940, disbanding before it received any aircraft.
The third and final incarnation of the squadron formed on 25 February 1941 around a nucleus provided by No. 207 Squadron. The new squadron was equipped with the troubled Avro Manchester, beginning operations on 8 April 1941. This aircraft was so unreliable that for a short time in the summer of 1941 the squadron had to supplement it with a number of Handley Page Hampden Is.
The much superior Avro Lancaster began to arrive in January 1942, and the squadron operated that type for the rest of the war, mostly with the main bomber force
but from April 1943 to April 1944 with the Pathfinder Force.http://www.historyofwar.org/air/units/RAF/97_wwII.html
