JANUARY 20, 1927 The Johnson " Twin 60 " taking off in a cross-wind. It is, of course, possible that the Johnson " Twin 60 " will fly on either of its two " Cherub " engines, in which case the criticisms fall away automatically. Pending the arrival in this country of more detailed information, one cannot say. In the meantime it is worth recording its production as an interesting experiment. For the time being all that is known concerning the ' ' Twin 60 " is that it is reported to weigh 860 lbs., and that with pilot, one passenger and 22 gallons of fuel it gets off the ground from standing start in 3 seconds (!), while the climb to 3,000 ft. is accomplished at the rate of 500 ft./min. The machine is credited with a top speed of 85 m.p.h., and the landing speed is given as about 22 • 5 m.p.h. The latter figure, at any rate, seems open to doubt. We have no figures for wing loading, but, even allowing for a high-lift section (that used appears from the photographs to be one of the Gottingen ',' tadpole " sections), a landing speed as low as 22 m.p.h. would seem to infer a maximum lift coefficient rather higher than appears likely to be attained. However, even if the landing speed is 32 m.p.h., instead of 22, it should be low enough to ensure a very considerable degree of safety. It is reported that the machine has been thoroughly tested out for taking off and alighting under particularly difficult conditions, and has been found to behave very well indeed. One of the accompanying photographs shows the machine taking off alongside what appears to be a road or railway embankment, presumably in a cross-wind with the wind coming over the embankment and causing a down-draught, and the cinematograph operators give the appearance of being rather nervous and very possibly experiencing a con- siderable up-draught! Features such as the two petrol tanks on the top plane. and the Reed Duralumin airscrews, as well as the twin rudders, can be seen in the photographs. The undercarriage is of the type using rubber rings in compression. The front legs are telescopic, while the lateral bracing is in the plane of the rear chassis struts. Some kind of wheel brake appears to be incorporated in the undercarriage. After their many successes at home and abroad, no surprise need be expressed at the choice of the Bristol " Cherub " engines, which may certainly be relied upon to do their share towards making the ]ohnson " Twin 60 " a success.

It was being flown solo by Capt. H. Spooner on the11th inst. In making a forced landing he got into a ploughed portion of a field and the machine turned completely over. The damage, however, wasvery slight and the machine was again in commission during the week-end. The Hampshire Aeroplane ClubREPORT for week ending January 14.—Total flying time, 10 hrs. 25 mins. ; instruction flying, 8 hrs. 40 mins. ; passenger flying, 1 hr. 15 mins. ; soloflying, 30 mins.

With Mr. Goodfellow :Mr. Williams, 15 mins. During the week Mr. Birley, Mr. Twemlow and Dr. Wade have all success-fully acoiumplished their height tests. One is filled with admiration for these hardy fellows. To the north lies Rivington Pike, With other nasty protuber-ances round about ; to the east and south-east and north-east lie the Yorkshire and Derbyshire ranges ; to the south lies the high ground of Staffordshire andthe Potteries, while to the west lie the Frodsham hills. With the clouds resting comfortably on all these excrescences and only small gaps of blue to climb int»these brave birdmen, armed only with an aneroid and a few days' iron rations., set out day after day in search of their " A " licences. One can only saythat they earn them. The palm this week, however, must be awarded t» Mr. Costa who, competing in the height contest, climbed a " Moth " until theaneroid struck work and, in the words of the old tale, a little dicky bird came out and sang " Nearer, my God, to Thee." It is really scandalous the way that important news items are kept backfrom the correspondent. Immediately on our return from Switzerland we rang up the aerodrome to inquire how much crashery had been committed iuour absence. We were told " none." On arrival at the aerodrome we found L.V. in the hangar with the undercarriage removed and the fuselage stripped." Aha ! " we said, pointing the accusing finger, " a crash." " Crash, sir ? " says the ground engineer, with a pained expression, " why, bless your heart,sir, that's nobbut a heavy atterrissage." Midland Aero Club.
