Michael Alsbury

Lore & Background

Michael Alsbury was born in Santa Clara, California, and grew up in Scotts Valley. He graduated as valedictorian from Soquel High School in 1993, was an Eagle Scout, and played soccer as a child. He earned a Bachelor of Science in Aeronautical Engineering from California Polytechnic State University in San Luis Obispo, and obtained his pilot's license at age 23. He married Michelle Saling, whom he met at Cal Poly, and had two children, aged 7 and 10 at the time of his death, living in Tehachapi.

Alsbury joined Scaled Composites in 2001, working as a project engineer and co-pilot. In April 2013, he served as copilot to Mark Stucky on the first powered flight of VSS Enterprise and SpaceShipTwo. At the time of his death, he had 1800 flight hours, 1600 of them as a project engineer and co-pilot with Scaled Composites. In 2013, he received the Ray E. Tenhoff Award for the most outstanding technical paper at the Society of Experimental Test Pilots symposium, along with Mark Stucky and Clint Nichols.

On October 31, 2014, Alsbury was test flying the Virgin Galactic SpaceShipTwo VSS Enterprise with Peter Siebold. The craft broke up in-flight, crashing in the California Mojave Desert. Alsbury was unable to exit the spacecraft, and his remains were found still strapped to his seat in the fuselage. Siebold survived. It was the ninth time Alsbury had flown aboard the aircraft.

Reader's Guide

Michael Alsbury's significance lies in his contributions to commercial spaceflight testing as a test pilot and engineer for Scaled Composites. He was part of the team that achieved the first powered flight of SpaceShipTwo, a milestone in Virgin Galactic's suborbital space tourism program. His death during test flight PF04 highlighted the inherent risks of experimental flight and led to investigations that shaped subsequent safety protocols. His legacy includes posthumous recognition: his name was added to the Space Mirror Memorial in 2020, and he was awarded the FAA Commercial Astronaut Wings in 2021. The dedication of a BBC One episode to him underscores his place in the narrative of human spaceflight. Alsbury's career, from Eagle Scout to award-winning test pilot, exemplifies the technical and personal commitment required in aerospace development.

Roots in the California Sky

Michael Tyner Alsbury entered the world on March 19, 1975, in Santa Clara, California, the son of Rich and Linda Alsbury. Though born in the Bay Area, he spent his formative years in the quieter community of Scotts Valley, where he developed a competitive drive that would define much of his life. A young soccer player and an Eagle Scout, he carried that same intensity into the classroom, earning the distinction of valedictorian when he graduated from Soquel High School in 1993. His fascination with flight was not a late discovery; it had been a constant thread since childhood. At twenty-three, he earned his pilot's license, and he went on to complete a Bachelor of Science in Aeronautical Engineering at California Polytechnic State University in San Luis Obispo. It was at Cal Poly that he met Michelle Saling, a partnership that would last twelve years and produce two children. At the time of his passing, the family was settled in Tehachapi, where his children were seven and ten years old.

Building the Future at Scaled Composites

Fresh out of Cal Poly, Alsbury walked straight into Scaled Composites in 2001, where he took on the dual role of project engineer and pilot. Over the next thirteen years, he accumulated a remarkable 1,800 flight hours, the vast majority—roughly 1,600—logged in that combined capacity at the company. His contributions were not limited to the cockpit; he participated in the engineering and design processes that brought experimental aircraft to life. In April 2013, he sat in the copilot's seat beside Mark Stucky for the first powered flight of the Virgin Galactic SpaceShipTwo, VSS Enterprise, a milestone that opened a new chapter in suborbital spaceflight. That same year, Alsbury, Stucky, and Clint Nichols were recognized with the Ray E. Tenhoff Award at the Society of Experimental Test Pilots symposium for the most outstanding technical paper presented. By the time of his death, Alsbury had completed nine flights aboard VSS Enterprise, each one pushing the vehicle's performance envelope and gathering the data needed to refine it for the future.

The Flight That Ended Everything

On October 31, 2014, Michael Alsbury was aboard the VSS Enterprise for test flight PF04, with Peter Siebold at the controls. The mission, like the eight before it, was intended to push the vehicle's limits and collect critical data for Virgin Galactic's suborbital program. What unfolded was catastrophic. The spacecraft broke apart in mid-flight, and the VSS Enterprise was lost entirely, its wreckage scattering across the California Mojave Desert. In the violent breakup, Alsbury was unable to free himself from his seat or eject from the fuselage. His remains were later recovered still strapped in place inside the wreckage. Peter Siebold, the pilot, survived the accident. For Alsbury, that flight was his ninth in the aircraft—a testament to the trust the program placed in him and the depth of his commitment to getting the vehicle right. His death on that October day brought a sudden and tragic end to a career that had been climbing steadily toward the frontier of human spaceflight.

Remembering Alsbury

In the weeks following his death, the aviation and space communities found ways to honor Alsbury's memory. On November 4, 2014, the fifth episode of BBC One's Human Universe, presented by Brian Cox, was dedicated to him; the episode featured a segment on Virgin Galactic test pilot David Mackay, weaving Alsbury's story into the broader narrative of commercial spaceflight. In 2020, his name was added to the Space Mirror Memorial, a lasting tribute to those who gave their lives in the pursuit of space. Then, in 2021, the Federal Aviation Administration posthumously conferred upon him the Commercial Astronaut Wings, a recognition that formally acknowledged his contributions to the emerging field of commercial spaceflight. These gestures—spanning a major television broadcast, a memorial inscription, and a federal aviation award—collectively speak to how deeply Alsbury's work and sacrifice resonated across the industry, even as his two children, aged seven and ten at the time of his passing, continued to grow up in Tehachapi without their father.
