20/12/42; First bombs dropped using OBOE as drop indicator. Target, the Cocking Plant at Lutterade, Holland. A/c taking part DK331, DK332, DZ317, DZ319 and DK321
31/12/42; First OBOE sky-marking, for the main bomber force, by Sqd/Lr. Bufton (DK331). Dusseldorf was the target.
01/06/43; 109 & 105 Sqds. join No.8 Path Finder Group, under Don Bennett.
109 Sqd. completed 149 sorties in No.2 Group, before joining No.8 Group. In the PFF. 109 Sqd. completed 5,411 sorties for the lost of 18 A/c.

31/09/45; 627 Sqd. moves to Woodall Spa and is renumbered as 109 Sqd. and continues in Bomber Command.
Examples of Types of Operations:

28/02/43; 109 Sqd. ground-marked for the main bomber force for the first time. The target was the dockyard area of St. Nazaire.
05/03/43; The first major bombing attack using OBOE Mosquitoes as bombing leaders. 442 heavy bombers, lead by 8 PFF Mosquitoes attacked the Krupps Works at Essen.DZ436,DK425,DK433,DK435 & DK430 were all successful in marking the target.
21/06/43; Mosquito BIX's used for the first time, because of their increased performance i.e. greater height & speed, OBOE could be used over a greater distance (OBOE worked by sending a signal by 'line of sight', so was restricted to the distance that it could be used).Krefeld was the city attacked. LR496, LR499, LR500 & LR503 (This was LR503 first sortie, another 212 would follow, which would make this a record number of sorties, for an allied aeroplane).
01/03/44; 109 Sqd. start daylight marking, again. Typical targets were V1 sites, airfields & communications, in readiness for D-Day.
06/06/44; 109 Sqd. mark targets in Pas-de-Calais. (see 105 Sqd.)
