Richard Branson's space flight on July 11th experienced a yellow caution light and later a red warning light due to a trajectory problem, which put the mission at risk. The pilots, Dave Mackay and Mike Masucci, attempted to address the issue but did not abort the rocket motor, and the ship flew outside its designated airspace. The incident has raised concerns about the safety culture at Virgin Galactic. The company has faced close calls and calamities in the past, including a crash in 2014 that killed one pilot and badly injured another.
