1947--GEORGE H. TRYON, III,
Secretary of the National Fire Protection Association, in the Quarterly of the National Fire Protection Association (Vol 40, No. 4) of April 1947 on page 264 states:
"Moving the landing gear inboard and strengthening the fuselage to absorb the shock of landing would eliminate applying stress to the fuel tank supporting structure. This revision of the commonplace has been accomplished in the Burnelli "lifting wing" design. Another feature of this latter type aircraft is the shifting of fuel tanks so that they are not in direct line with the power plants and their exhaust outlets."
