HE Royal Aero Club is to be congra- tulated upon the meeting which lias been arranged for this week-end. If one may judge by the list of entries, pub- lished in this issue of FLIGHT, and by the official programme, the three days at Lympne should prow among the most interesting events of recent years. No less than 25 machines have been entered, of which there is reason to believe that practically all will face the starter. Few of the machines are, it is true, of very modern type, but, on the other hand, visitors to Lympne will have an opportunity of comparing some fairly old aeroplanes with some of the most recent tpye, a fact which should in itself lend interest to the proceedings. While on the subject of the competing machines, it may not, perhaps, be amiss if we explain, for the benefit of those of our readers who are not familiar with the system of identification, the manner in which the identification letters are arranged, and their signifi- cance. Great Britain has been allocated the initial letter " G," and in the identification of British aero- planes this letter must be followed by a vowel : the one chosen being " E." When the present system of identification came into force, the first machine registered received the identification G-EAAA ; the next one received the letters G-EAAB, and so on, until G-EAAZ had been reached. A fresh start was then made with G-EABA, and so forth. It will thus be seen that from the identification letters which a machine carries, one is able to form a fairly accurate estimate of its " period." To take an example, G-EACZ is obviously fairly old, in view of the fact that it is in the " A " series. Also it is obviously the last of the EAC series, and the next one following it would be EADA. Perhaps these brief notes on registration letters may serve to indicate that the apparently meaningless jumble of letters is in reality very significant, and once this fact is pointed out it becomes possible to form a much clearer conception B 2 1:,
