Blue Origin, the aerospace company founded by Amazon’s Jeff Bezos, made history on Tuesday.

As announced in June, Jeff Bezos and his brother Mark were aboard the company’s New Shepard craft—named after Mercury astronaut Alan Shepard—for what the former Amazon president and CEO (and current executive chairman) described as “the greatest adventure with my best friend.”

The mission, marking Blue Origin’s first human flight, saw 82-year-old crew member Wally Funk becoming the oldest person to have ever flown in space. Meanwhile, 18-year-old New Shepard crew member Oliver Daemen became the youngest.

“This marks the beginning of commercial operations for New Shepard, and Oliver represents a new generation of people who will help us build a road to space,” Blue Origin CEO Bob Smith said when detailing the mission earlier this month.

Speaking with CNN’s space correspondent Rachel Crane ahead of Tuesday’s brief flight, which itself was closely preceded by a similar act of travel from Richard Branson, Bezos addressed the criticism many have shared amid news coverage of wealthy space-bound men.
