Who Are the Crew Members Aboard the Virgin Galactic Flight?

The pilots are David Mackay and Michael Masucci.

In addition to Mr. Branson, three Virgin Galactic employees joined the flight to evaluate how the experience will be for future paying customers. They were Beth Moses, the chief astronaut instructor; Colin Bennett, lead operations engineer; and Sirisha Bandla, vice president of government affairs and research operations.

On Sunday’s flight, Ms. Bandla was to conduct an experiment from the University of Florida that looks at how plants react to the changing conditions — particularly the swings in gravity — during the flight, part of research that could aid growing food on future long-duration space missions.
