Alternatively you can set a craft to "stay", [and land it if necessary] and then open the doors, and switch to the actor you want to load on board, and fly the actor into the "tractor beam", which is the area between the two yellow dotted lines. You will then hover into the doors of the craft.
This is much better for rockets, since they generally have their doors on the sides.
Rockets are meant to land to do their stuff, while dropships are made to drop/abduct on the go.
Devs, get this in the tutorial for goodness' sake.
