I spent a long time trying to figure out the details of how the photoflashes worked, i.e. time before flash, what kind of area could be lit with them for photography, altitude flown for release etc. So to hear from someone who saw this from the ground was very interesting.
I do have some 13 Sqn
PR contributors onboard who did talk about flashes and para flares. The consensus was night photography was not popular because in a war situation it would have of course been fairly easy to plot the position of the offending aircraft from the ground and deal with it. Of course anyone here has had operational experience (perhaps any Indian AF pilots?) I would be very keen to hear how it performed during the real thing.
PR pyrotechics are an interesting subject; similarly if anyone knows armourers who fitted them that would be useful too.
Hipper - good link, I have a lot of AP Manuals on PDF - they have been very useful in building Canberras for MS Flight Sim I can tell you!
