The names and addresses of the writers, not necessarily for publication, must in all cases accompany letters intended for insertion in these columns. GETTING OFF IN A CALM[2192] With reference to the interesting article in your issue of May 9, p. 382, has Sqd.-Ldr. Scott tried air'ubrication ? I found our normal run of 60 to 70 yards before "unsticking"could be reduced by air lubrication to 30 to 40 yards when there was no wind.This might not be so with big weights and high speeds. 1 was dealing with speeds under 30 m.p.h. and weights well under four figures all up. E. W. WAKEFIELD,L, May 13, 1929 Late Lakes Flying Co. THE FIRST SPIN1^193' In reply to your correspondent's letter with reference first spinning, deliberately carried out with success, Ilike to state that the late Major F. W. Gooden carried bort? ser*es °* experiments on a FE 8, spinning the machine°- ways three times and then wrote a report on spinning and how to do it which was circulated throughout the service. « may be recalled that at this time, approximately"^y. 1916, several fatal accidents happened on this type Tif similar tvPe of machine. i he experiment was done at Farnborough, where Dr.'ndeman was also employed in scientific research, but he aaQ not at that time learnt to fly. lour correspondent will no doubt notice an interestingS11 »ilanty in the names. L. R. TAIT COXLondon Aerodrome, May 14, 1929. ? THEORY OF LONG-DISTANCE FLIGHT [2194] In his article on the theory of long-distance flight in the April number of the AIRCRAFT ENGINEER, Mr. Nebesar has approached the problem of long-distance flying in a very original and interesting way. Does he not, however, over- stress the need for flying at the attitude of minimum drag ? He appears to take it for granted that an aeroplane with a high aspect ratio must fly slowly because the speed at which minimum drag is obtained is lower than it would be if a low aspect ratio were used. In the case of machines which are within normal pro- portions, it is usually true that those of high aspect ratio will fly with less power, at the same speed, than those which are of low aspect ratio but otherwise similar. Some caution would be advisable in the application ofMr. Nebesar's theory, for while he admits that " 0 " is a variable quantity, he nevertheless assumes it to be constantwhen he differentiates the expression for drag so as to find its minimum values and the speed at which it occurs. Inpractice this would lead to serious error both in resistance ' and speed. In any case, even if the minimum resistance did occur when the induced resistance coefficient wa? equa i to the sum of the profile and parasite resistance coefficients, would it not be better to reduce the parasite resistance rather than increase the induced resistance in order to obtain that con- dition ?
