Description: Martins six jet XB 48 was ordered in 1944 as part of a design competition for a postwar jet bomber An odd mixture of the conventional and the innovative , it lost out to Boeings swept wing B 47 and was destined only to become one of aviations brief oddities It pioneered the use of tandem main landing gear , which lived on in other designs Three General Electric J35 A 5 engines were mounted in a single housing beneath each wing , creating a pair of tunnels for airflow Air passing through was supposed to help cool the engines and to boost the planes airspeed by means of a venturi effect This feature , however , proved to be overly optimistic , leading a test pilot to report that he could almost see the air piling up ahead of each wing in flight
