My camera breaks after I crash my plane. Can someone help me?

So I have a game with planes but there's a problem with them. Sometimes if I crash with them the camera breaks and stays where my character died even tho my character has already respawned. It says that Head is not a valid member of Model. I have no idea what to do so I'm hoping that someone here could help me with this problem.

repeat wait() until script.Parent.Welded.Value --This line makes the plane invulnerable to weapons when it is still welding
wait(0.1)
local Plane = script.Parent --Lines 3 - 10 set variables
local AutoCrash = Plane.AutoCrash
local Ejected = Plane.Ejected
local Engine = Plane.MainParts.Engine
local CanCrash = Plane.Customize.CanCrash
local Force = CanCrash.Force
local Crashed = Plane.Crashed
local Parts = {}

		Explosion.Parent = game.Workspace
		Explosion.Position = Engine.Position
		Explosion.BlastRadius = Plane:GetModelSize().magnitude / 1 --This makes the BlastRadius the size of the plane
		Explosion.BlastPressure = 1e1
		if Engine:findFirstChild("Thrust") then Engine.Thrust:Destroy() end
		if Engine:findFirstChild("Direction") then Engine.Direction:Destroy() end
		delay(5,function() Plane:Destroy() end) --This removes the plane after 5 seconds
	end
end

function GetPlaneParts(Model) --This function gets all the parts on the plane
	for _,v in pairs(Model:GetChildren()) do

					Explode()
