Notes:
S/L A.H.Oakenshott carried out 1st operational sortie, 31/05/41, for 105 Sqd. in W4072.
In 1st year of operations: 524 sorties for the loss of 35 a/c.
105 Sqd. was the 1st fully operational squadron in the RAF(not included odd a/c or units eg photo recon flights)
Many bombing raids (in this early period), were carried out in daylight at low level. 105 Sqd. developed a bombing technique which enabled all the attacking a/c to attack the target before the leading a/c's bombs went off. This technique consisted of two flights, the first at low level (50-100ft), and the second flight attacking in a shallow dive, starting from about 1500ft. The bombs used had an eleven second time delay, before exploding. So timing was of the essence! The idea was to get both flights across the target quickly, before the defences could react. Thus the speed of the attack made it safer for the second flight.
01/06/43: 105 Sqd became part of No.8 Group Path Finders Force, under Don Bennett. After joining 8 PFF 105 Sqd went from low level daylight raiding to high altitude (28,000ft) marking and bombing.
105 & 109 Sqds. the only 2 Mosquito/Oboe PathFinder Sqds. which specifically marked targets for Bomber Command.
During this period with 8 PFF 105 Sqd. flew 4947 sorties for the loss of 10 a/c. After 109 Sqd. this was the highest number of sorties within 8 PFF.
Many Mosquitos flew over 100 sorties, but LR503, Fbar-Freddie flew a record 213 sorties.
01/02/46; 105 Sqd. is disbanded at Upwood.
