I finally got a chance to watch the SpaceX launch, and it was quite impressive. The insane thing is the plan is to eventually churn out 1 brand new Starship every day. That compared to NASAs 6 space shuttles.
The 1% chance of death on every space shuttle launch will need to be improved if they are to occur every day.

It's the lightest weight inert gas, is my guess. Helium is also used to force propellant to motors as the tanks are rapidly depleted.
