Rocket works fine the first time, but launches way too quickly the second time?

Hello, I have built and scripted a rocket that is supposed to count down, launch, and then respawn. The rocket's first launch works perfectly, but after respawning the second launch is way too fast. I have unanchored the rocket after it has respawned and it has flown up into the air. I thought it had something to do with the position of the rocket when it respawned but I had no luck. When I walk into the rocket when I enter the game nothing happens, but after it has been respawned it flings my character.

Button = script.Parent.ClickDetector
Rocket = game.Workspace.RocketLauncher.Rocket
Screen = script.Parent.Parent.Screen.SurfaceGui.TextLabel
Engine = script.Parent.Parent.Parent.Rocket.RocketEngine

PosX = Rocket.Position.X
PosY = Rocket.Position.Y
PosZ = Rocket.Position.Z

Button.MouseClick:connect(function()
	if Rocket.Parent == game.Workspace.RocketLauncher then
	game.Workspace.RocketLauncher.Rocket.Anchored = true

	Screen.Text = "3"
	print(3)
	wait(1)
