Dear W/C. Cheshire,
Herewith the lecture of which I spoke.
If you have any comments I should be grateful for them. As you will see we have what amounts to three models which viewed from 6 yards standing up represents 1200ft at 1200 yards, 450 ft and 450 yards and 150 ft and 150 yards, the last being a bit optimistic, but when we asked for the model at the beginning we didn't know much about the very low point. However, fortuitously it has turned out the right size since it covers really both flares and very low work without an extra model. These distances are judged on the worst viewing angle from the Mosquito, since we like to teach in such a way that the synthetic is worse than the real.
A point which still worries me, from the instruction point of view, is how to know you are at 300ft or so. I'm never happy about altimeters when they get over 50 miles away from base, and the Radar type would be impossible to get for our quantity even if they had no limitations. Is here any crew work that one could standardise from the teaching standpoint? I have been unavoidably vague in the script – one watch the horizon and one the ground etc. (“if you can, this kind of thing”).
A scheme which might interest you has been tried lately by Mr Thomas of Leamington Spa (made the models Bomber Command use. He makes rapid artist scetches[sic] of any target as seen from any height, time (night or day), bearing, from a vertical photograph. I introduced him to 2 Group but don't know how far they have got. He may be of some help to you. I have not mentioned you to him. You may, of course, know him. Leamington Spa 2190, Ministry of Home Security – Camouflage.
Thanking you for your help.
