Bezos and his Blue Origin crewmates trained for 14 hours. These are the requirements they had to meet.

On Tuesday, Jeff Bezos and three other people became astronauts as they flew to space on Blue Origins' first test flight with humans. While NASA astronauts train for months, Bezos, his brother Mark, 82-year-old aviation pioneer Wally Funk, and 18-year-old student Oliver Daemen trained for just 14 hours. 

During a news conference Sunday, Blue Origin launch director Steve Lanius said the astronauts began training on Sunday, two days before the launch.  The 14-hour training, which complied with Federal Aviation Administration regulations, was split between two days, Lanius said. It consisted of classroom instruction, demonstrations and practice in a training capsule.
