However, experience in the United States of America with the only existing full-scale high pressure F.I.D.O. system has thrown considerable doubt on the efficacy of the system developed there as an acceptable aid to civil aviation. My Department is closely watching the American results and, in the meanwhile, are re-examining the costs and methods of financing a possible installation at London Airport to see whether a more attractive proposition can be made to the operators than the offer they were unable to accept in 1951.
