I remember one celebrated crew was all Australian except the bomb aimer whom they called their ‘Pommie Mascot’. 
The captain was a WO the rest Flight Sgts and Sgts, the bomb aimer was a flying officer. HQ RAAF kept up a running 
question as to why this crew were not all commissioned. They just kept refusing saying it would kill their luck. 
They completed an excellent tour. The only black spot was when they had flying control instruction to land “call 
funnels on approach” on return from ops. Just what they lined up on I don’t know, but the next thing I knew they 
called up as having landed in the Humber in line behind the runway but six or seven miles short.
