Spawning a pawn (propulsed from another pawn) in blueprint

is for a multy game

the players spawn inside the main ship (the map who simulate the interior of the ship)
if one player go on the control room and go in front of one console and press E the player can control the main ship (move it,shoot,etc) if he press e again he will return in the control room)(that not working yet that why i have created this question too How to create a Blueprint Button that controls a pawn blueprint? - World Creation - Unreal Engine Forums)

if players go in the hangar room and go in front of small ship and press e (the player who have pressed e will be spawned into the small ship eject from the main ship and pilot the small ship )

if players go in the launchable exist into the big ship pawn he will be able to be aboard the main ship on the hangar room (so the small ship pawn will be destroyed and spawn the palyer into the room)
