The distribution discussed by Mayhew and Vajda (J.S.S. Vol. vi, 1946, pp. 67–75 (70)), is the binomial with negative index (having origin, i.e. first term, at n instead of o), about which a good deal has been written, and their problem is the one discussed by Yule in 1910 (J.R. Statist. Soc. Vol. LXXIII, p. 26). The authors base their proof on an idea of Laplace, but the full power of the characteristic function derivation can be seen if we go further than they did. The results are of some interest, particularly as Kendall (Advanćed Theory of Statistics, Vol. 1, §5.13) does not go beyond deriving mean and variance by the elementary method in this case.

I have been asked to give you some idea of the activities which occupied me for four years of the war, namely, my duties with the Admiralty. For obvious reasons it is not possible for me to give in detail many of my impressions or the problems that arose in the work which was mainly directed to the end of securing the right number of the right type of Naval Aircraft at the right place at the right time. In practice the emergency of the problem precluded the use of sophisticated methods, and recourse had to be made to practical measures designed to provide a fair approximation to the answer sought.
As an instance of the actuarial nature of the problem involved it may be noted that the life of an aircraft is made up of three components:
(a) a period when, although serviceable, the aircraft is ineffective through being in transit, etc.,
(b) a period when it is effective and in use (including that in ‘ready reserve’), and
(c) a period when the aircraft is ineffective while undergoing repair, etc.
