Morton Lee Lewis (June 2, 1913 – July 6, 1959) was a U.S. Navy officer, aviator, and balloonist. He is best known for his role as co-pilot in the U.S. Navy’s Project Stratolab high-altitude manned balloon flights during the 1950s, which advanced aeromedical and atmospheric research. In 1956, Lewis and his commanding officer, Lt. Cmdr. Malcolm D. Ross, set an altitude record in a manned balloon flight and were later awarded the Harmon International Trophy for their achievement. Lewis was posthumously awarded the Distinguished Flying Cross for extraordinary aerial achievement during a 1958 stratospheric flight.
Morton Lee Lewis was born on June 2, 1913. Details of his early life and education are not widely published, but he pursued a career in naval aviation and attained the rank of lieutenant commander. By the mid-1950s, Lewis was assigned to the U.S. Navy’s aeromedical and high-altitude research programs.
High-altitude balloon flights
In the 1950s, Lewis joined Lt. Cmdr. Malcolm D. Ross in a series of experimental high-altitude balloon missions conducted by the U.S. Navy under Project Stratolab. The program aimed to study atmospheric physics, cosmic radiation, and the physiological effects of extreme altitude on human pilots.
On November 8, 1956, Ross and Lewis piloted the *Stratolab I* balloon to an altitude of approximately 76,000 feet (23,165 m), establishing a new record for a manned balloon flight.[1] The mission gathered valuable data on the upper atmosphere and demonstrated the feasibility of manned operations at near-space altitudes.
Two years later, on July 26, 1958, Lewis again served as co-pilot to Ross during the *Stratolab High III* mission, launched near Rapid City, South Dakota. The balloon ascended into the stratosphere to conduct scientific observations and physiological tests.[2] During the flight, Lewis tested a newly developed sealed-environment gondola system designed to maintain internal pressure and temperature in the upper stratosphere. He voluntarily removed his helmet and oxygen mask for the duration of the mission—at altitudes up to 82,000 feet—to evaluate the system’s safety under real conditions.
Distinguished Flying Cross
Following the *Stratolab High III* mission, Lewis was posthumously awarded the Distinguished Flying Cross for extraordinary achievement while participating in aerial flight from July 26–27, 1958. The official citation, published in All Hands magazine in December 1959, reads:
The President of the United States of America takes pride in presenting the Distinguished Flying Cross (Posthumously) to Lieutenant Commander Morton L. Lewis, United States Navy, for extraordinary achievement while participating in aerial flight as Pilot and Observer of a two-man, Navy Strato-Lab balloon and gondola during a daring and hazardous ascent into the upper stratosphere on 26–27 July 1958. Testing aloft, under actual operating conditions, a new-type, sealed environment in the gondola, Lieutenant Commander Lewis determined the maximum effectiveness of this entirely new system, voluntarily removing his helmet and oxygen mask, except for take-off and landing, for the duration of the flight at pressure altitudes ranging from 29,500 feet to 82,000 feet and thus risking his life in the event of decompression. Contributing an unofficial world endurance record for sustained flight in the stratosphere of 34 hours and 39 minutes, he also participated in approximately 27 other scientific experiments.
Awards and recognition
- Harmon Trophy (1956) — jointly awarded with Malcolm D. Ross for record-breaking high-altitude balloon flight.[4]
- Distinguished Flying Cross (posthumous, 1959)
Death and legacy
Morton Lee Lewis died on July 6, 1959, at the age of 46. He was interred at Arlington National Cemetery. His pioneering work in high-altitude flight contributed significantly to the development of manned aerospace programs and early astronaut research.[5]
