SpaceX has more experience than anyone else in lighting dozens of rocket engines at once. They've never had a Falcon Heavy failure in 5 years of operation.

It's not the number of engines that's the concern, it's the sheer power. This is the most powerful rocket ever made. It produces as much thrust as two Saturn Vs. The danger here is that something on the ground gets damaged by the sheer magnitude of this thing. And failure here is very possible.

Lmfao imagine thinking Elon is on Russia's side, especially when it comes to Roscosmos.

Elon is a lot of things. But Russian puppet is not one of them. He famously started SpaceX because he tried to buy a rocket from Russian oligarchs and they literally spat in his face. He's repeatedly joked that if he accepts an invitation to go have dinner with the head of Roscosmos, they'll serve him Polonium tea.

Here's a hint: the main reason Roscosmos is in shambles today, and that Elon is one of the richest people in the world, is because Elon has managed to cannibalize their main foreign income stream and direct it into his own pockets by taking all of their customers.
