Ah yes, that would increase the separation quite quickly.

I guess they do the relight test after the simulator deploy because it is a higher risk activity - the pez dispenser is very unlikely to cause a RUD.

Apart from the spectator value of mounting a camera on one of the Starlink simulators, how much value would such a camera have to SpaceX in being able to monitor the re-entry? How long before the simulator was too far away / too hot to be able to continue transmitting useful images?

How will the transition from 5 to 3 engines on the Booster landing burn add additional redundancy? How is that different from going straight to 3 engines?

Previously the 3 engine landing burn was for about 16 seconds. If there was a 5 second burn with 5 engines then that would be followed by a 7 or 8 second burn with 3 engines, giving a total elapsed burn time of 13 seconds.

Is there a gap between the 5 engine burn and the 3 engine burn or will they just switch off two engines after 5 seconds. Does that mean that they can then choose which two to turn off and avoid the need to allow for the 0.2 seconds engine startup time that would be needed if there was a failure of one of the 3 engines. Is that the only benefit of a 5-3 landing burn?

Is there a visualization anywhere of the maneuver that is intended to mimic the approach path to the launch site? Will it come in over Mexico and then do some kind of wiggle? What population centers do they need to avoid?
