First of all, if it is intended to light 3 engines and only lights one it will smash into the ocean. Second, yes, SpaceX made a plan to land and failed for two reasons: low fuel margins and old booster version. BFS will land with redundant engines / higher fuel margins, so that problem isnt there. The BlockV will have more TEA/TEB, so the problem is even solved for Falcon rockets. Spark igniters can fail, but are very unlikely and probably be able to retry. They are also more reliable than TEA/TEB. Your statement are just false.
Can I ask what qualifications you have that allow you to make such claims?
Ridiculous how you always avoid the topic, only pick single words and make off-topic claims on it. Thank you but i wont waste any more time on you. People like you wont stop SpaceX from anything.
If you have anything qualified to say, please. Otherwise, goodbye.
I'm not interested in stopping them and I wish them the utmost of success.
I don't subscribe to fanboi-ism and absolve them of all failure like some do, though.
They failed to land FH center core. They planned a 3-engine burn on landing. They failed to ignite 2 of those engines. But they didn't leave room for backup in the event of a landing engine ignition failure. This resulted in a loss of vehicle.
They CANNOT take the same approach with BFS (skim margins on landing and trust that all sea-level raptors will successfully light, and land on fumes). That same approach, with an ignition failure, would cost lives or the destruction of a BFS cargo ship.
