Jeff Bezos wishes Branson ' successful and safe' flight ahead of his journey to the edge of space

Amazon founder and executive chairman Jeff Bezos on Saturday wished fellow billionaire Richard Branson luck ahead of his historic journey to the edge of space scheduled to take place Sunday, Business Insider reports.

"@richardbranson wishing you and the whole team a successful and safe flight tomorrow," said Bezos in an Instagram post on Saturday afternoon. "Best of luck!"

Branson's trip Sunday comes just nine days ahead of Bezos' own planned trip to space with his brother and other crew aboard his company Blue Origin's New Shepard spacecraft. Branson will become the first founder of a space company to launch to the edge of space.

"Ever since I was five years old, I've dreamed of traveling to space," Bezos said in a previous Instagram post. "On July 20th, I will take that journey with my brother."
