At 40,000 feet the plane would dive into a formation of enemy aircraft at an estimated speed of up to 875 km/h and clip their wings or tail surfaces with its own reinforced wings, for this reason they gave the XP-79 the nickname: "Flying Ram". The pilot would operate the aircraft from a prone position, permitting the pilot to withstand much greater g-forces in the upward and downward direction. The pilot controlled the XP-79 through a tiller bar and rudders mounted below; intakes mounted at the wingtips supplied air for the unusual bellows-boosted ailerons.
