This was the first aircraft to complete a round trip from New York to London. The following description of this aicraft is from Aerofiles.com.
Harry Richman, a well-known entertainer of the time, and an aviation enthusiast and part-time pilot, sponsored the first round-trip flight between New York and London. Henry T "Dick" Merrill, chief pilot of Eastern Airlines, would captain the V1-A [NC13770]. Extra fuel tanks and a 1000hp Wright Cyclone with a constant-speed, two-blade prop were installed, and some 41,000 Ping-Pong balls were stowed in the hollow recesses of wings and fuselage—if forced to ditch, the airplane would certainly float! With war looming in Europe, Richman christened the Vultee Lady Peace. The Vultee ended up in Newfoundland due to the pilot inadvertently dumped some fuel and then had insufficient fuel to reach New York. The Vultee suffered some minor damage in an emergency landing at Musgrave Harbour, Newfoundland. Repairs were made at Musgrave Harbour then flown to Harbour Grace airstrip then on to New York.
