Low earth orbit travel is not yet as reliable as commercial aviation because the sample size of successful flights is still statistically small.

“a few hundred is not that many right you think about how many airplanes people tried to build in the early 1900s and how many crash failed and from the films it looks like 100% of them I saw the the film fil other words 100 or a thousand isn't that big a sample size really”

Rockets launch vertically to gain speed and clear the atmosphere before transitioning to a horizontal trajectory, which is the most efficient path for achieving orbit.

“the only reason it tries to go up first is because it's trying to build up speed because it will then start curling sideways it starts moving horizontally because the best way to get into orbit or out of the gravitational well of a planet is to travel at a tangent not straight up vertical”

He asserts that rocket engines work on the principle of recoil, expelling mass to create thrust, which functions effectively in a vacuum.

“That's all a rocket engine is is it's expelling mass. It's it's shooting mass mass flow propellant as fast as possible. Supersonic, you know, and they're they're shooting it >> out as the faster you throw mass, the more reaction it has against you,”
