Hmmm . food for thought, I'll take a shot. I’m thinking along these lines:
Lets say the trip is from Planet A to Planet B, the distance being 10 light hours. Say the craft could travel at twice the speed of light. 5 hours into the trip, the observer on B would see the craft on the pad because it is right there and would be immediately visible. If the observer then looked through some kick-ass telescope and looked at A, they would see the craft on the launch pad because the visible light from A is 10 hours old.
As for the journey of the craft itself, light from later parts of the journey would be visible to the observer before earlier parts, because it’s starting from a point closer to the observer and has a head start because the craft is moving faster than light. Light given off earlier in the trip is still lagging behind at lightspeed x1. I guess I would conclude from all that that you actually would see the journey in reverse from the landing pad to the launch pad. Or more precisely, from the landing pad to the point where the craft initially exceeded light speed. I guess it would sort of go like this:
You’d see the craft going backwards from the landing pad.
At a point not far from the launch site, the craft would suddenly disappear and instantaneously reappear on the launchpad.
You’d see the launch.
You’d see the craft taking off and accelerating, then disappear.
All the while, the craft has been visible sitting on the landing pad.
Ok, now I think I’m going to go and have a lie-down.
