The video shows the flight of a homemade rocket so powerful that reached almost a mile (1.6 kilometers) of height. It was called “Hermes” by his anonymous maker, after the interplanetary ship used by Matt Damon in The Martian.
It was a level 2 certification rocket. The engine was an Aerotech J415W with an RRC2 controlled dual deployment.
“Here’s a video of my successful Level 2 Certification attempt on March 20, 2016 at the SMASH/MMAR launch at Muskegon, Michigan”, says in the description of the video.
