Looks like they are going to follow the community suggestion of lighting all 3 raptors, and 'IF' all three light then turning one off.
Elon kinda admitted they were a bit dumb, and it does seem obvious really.
If you must have 2 engines running otherwise you crash, and you only try and light 2, you get 1 fail and your crash.
Lighting up 3, gives you more of chance, until you can be 100% sure every engine will light every single time, which seems a risk at anytime.
I hear SN10 and SN11 are the same design,
But the next one SN15 (they scrapped the ones in between) are a bit different.
Though I'd not seen what the actual differences are.
Anyone?
