First launching of a two-stage rocket-propelled research model, the Tiamat missile, which employed six rockets as boosters, had automatic stabilization, its maneuvers were programed, and its testing was the first research program of the NACA's Wallops Island Station. References: 17 .

Goddard's rocket team ends its work at the Naval Engineering Experiment Station at Annapolis, Maryland. During the previous three years the team had developed a variable-thrust rocket motors. This required hundreds of proving-stand tests, but eventually producing a successful motor, later used on the Bell X-2 rocket plane. References: 482 .
