YOUR REF. GLC/DO. 17th April 1944

Wing Commander G.L. Cheshire, D.S.O., R.A.F., R.A.F.
No. 617 Squadron,
Royal Air Force Station,

My dear Cheshire,
Firstly, very warmest congratulations from all here on the award to you of the second bar to your D.S.O. which I see announced today. You may well believe that everybody at these Works who kn6ows what happened a year ago takes a most lively interest in the doings of 617 Squadron.
Secondly, many thanks for your letter of the 13th enclosing two further bomb plots. I will have these analysed and send you copies in a few days' time.
It is an interesting point about the first plot of 500 bombs that it does not fall in with the normal or Gaussian distribution, as on the whole your probability curve appears substantially better than would be given by theoretical standards. We shall be interested to see what sort of results the nest two plots give.
You will by this time, I hope, have heard of the great success which has attended the dropping of one inert and two live Tallboy M's.
P.T.O.
[page break]
The live stores gave depths of penetration between 60 and 80 feet in gravel, sand and clay with excellent detonation. The films show that they are perfectly stable throughout their flight, and I hope that we have therefore provided you with a new and effective weapon.
With kindest regards,
Yours very sincerely,
[underlined] B.N. Wallis. [underlined]
