Wat. It's a rocket, it doesn't 'suck up' anything except what's coming through the turbopumps. The engine starts are staggered to minimize stresses on the thrust structure. For the Saturn V:
"At 8.9 seconds before launch, the first stage ignition sequence started. The center engine ignited first, followed by opposing outboard pairs at 300-millisecond intervals to reduce the structural loads on the rocket. When thrust had been confirmed by the onboard computers, the rocket was "soft-released" in two stages: first, the hold-down arms released the rocket, and second, as the rocket began to accelerate upwards, it was slowed by tapered metal pins pulled through dies for half a second."
- smegel 9y agoMaybe "blown" is a better word, but the point is the only thing stopping exhaust going up another nozzle is it's own pressure. I read about it here I think: https://www.space.com/38016-spacex-falcon-heavy-rocket-maiden-launch-success-chances.html https://www.space.com/38016-spacex-falcon-heavy-rocket-maide... > If one engine doesn't ignite internally as it should, you will get a flame front that travels back into the engine." > "That creates a pressure spike, and that can cause what we call 'rapid unscheduled destruction' — and that's bad,"
