This same short span produced very little lift at low speed, which resulted in extremely long take-off runs and frighteningly high landing speeds.[7] In an SST design, this would have required enormous engine power to lift off from existing runways, and to provide the fuel needed, "some horribly large aeroplanes" resulted.[6] Based on this, the group considered the concept of an SST infeasible, and instead suggested continued low-level studies into supersonic aerodynamics.[6]
