,ANE Those wishing to get in touch with others interested in matters relating to gliding and the construction of gliders are invited to write to the Editor of FLIGHT, who will be pleased to publish such communications on this page, in order to bring together those who would like to co-operate, either in forming gliding clubs or in private collaboration. THE informal discussion which took place at the Institute of Aeronautical Engineers on Friday of last week helped to bring into prominence the urgent need for a relaxation of the restrictions at present surrounding flying, and more particu larly private flying of machines not being flown for payment or hire. Commander Harold Perrin mentioned that the Royal Aero Club was taking up strongly the matter of light 'planes' with the Air Ministry, and we now learn that there is every likelihood of the stipulations as to ground engineers' certificates, etc., being abolished in the case of privately owned machines of this class. It is to be hoped that this report is correct, as the relaxation of the restrictions would do more than could any other single thing towards popularising the light 'plane. At the moment we do not know what it is pro posed to do regarding airworthiness certificates, but we do think that the Air Ministry might very well leave it to indi vidual constructors to judge whether or not a machine was sufficiently strong. It is not likely that a manufacturer would jeopardise the good name of his firm by building unsafe machines, and the release from Government inspection of materials, erecting, etc., would do much towards lowering the price at which machines could be sold. NATURALLY we do not suggest that any amateur should be given a free hand to build a machine out of any sort of junk he could pick up, and then go flying across country to the risk of everything and everybody below, but responsible firms could, we strongly maintain, be given quite a free hand. * * * LIEUT. THORET has been making fresh gliding experiments in Northern Africa. This time he has visited Algier, where, at Nostaganem, he has remained aloft for two hours. With a passenger he.stayed up for 16 minutes. As in the Biskra experiments, Thoret used a Hanriot H.D.14 school machine, and the glides were, of course, made with engine stopped. A LIGHT 'plane meeting is to take place at the Brussels Aerodrome (Evere) on June 16 and 17. Competing machines are to be limited in engine capacity to 1,100 c.c. for single- seaters and to 2,000 c.c. for two-seaters. * * * QUALIFICATION tests will be carried out on June 16 over the course* Brussels-Gossoncourt-Bierset and back. The actual competition will include take-off tests, landing tests and dismantling tests. For the take-off tests it is required to leave the ground in the shortest possible distance, which will be measured from the starting line to the point where the wheels definitely leave the ground. * * * SIMILARLY the landing tests will consist in making the shortest possible run after touching the ground, measured from the point where the wheels first touch to the spot where the machine has come to rest. * * * THE dismantling and transport tests will consist in folding the wing, transporting the machine a distance of 100 metres on the ground, take it between two posts 2J metres apart, erect the wings, and make a demonstration flight in order to show that the machine is fully erected and fit for flying. One hour is allowed for this test. * * * ONE mark will be deducted for each metre of the take-off and pull-up, and one deducted for each minute occupied in the dismantling and transport test. The total classification will be obtained by the addition of the negative marks in the three sections, the competitor with the smallest number of marks being placed first. * * * THE prizes to be awarded total a value of 35,000 francs. The competition is of an international character, and British machines will thus be allowed to compete. It is to be feared, however, that no British machine will be finished in time to be thoroughly tested before the Belgian competition. The entrance fee is 100 francs, which will be refunded to machines actually taking part in the tests. For all information relating to the competition readers are asked to write to the Secretariat de la Commission Sportive, Aero Club de Belgique, 73, Avenue Louise, Brussels.
