SpaceX has released video of its Falcon 9 first stage splashing down vertically in the ocean.
The video is not very good, but at one point you can clearly see for a flash that the first stage is vertical and appears to be hovering above the water.
For decades engineers and managers in the aerospace industry have said that returning a first stage vertically made no sense. Elon Musk insisted that SpaceX try. It appears he and his company are now going to prove that everyone else was wrong about this.
