Ships that have made a hyperjump are only pulled into orbit by the planet's warpwell if they end up within a box (-2,-2)-(+2,+2) from the planet. If a ship lands outside that box but still inside the warpwell, it will not be pulled in since it's warp is reset to 0 right after the hyperjump.
and yes the warp is set to 0 upon completing a HYP Jump. For some strange reason, I always thought you still had to start out at warp2 or better
Some people spend an entire lifetime wondering if they made a difference.
The US Marines don't have that problem.
