Why won't my player move while they have the parachute?

This script creates a parachute when the player joins and they float down to the baseplate. It works perfectly, but I can't move around while I'm falling. How do I fix this?

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
		
		-- create the parachute
		local Parachute = Instance.new("Part", char.Torso)
		Parachute.Size = Vector3.new(2, 1, 2)
		Parachute.CanCollide = false
		
		local RealParachute = Instance.new("Part", char.Torso)
		RealParachute.Transparency = 1
		RealParachute.CanCollide = false
		
		-- parachute mesh
		local Mesh = Instance.new("SpecialMesh", Parachute)
		Mesh.MeshId = "http://www.roblox.com/asset/?id=85027689"
		Mesh.TextureId = "http://www.roblox.com/asset/?id=85027535"
		Mesh.Scale = Vector3.new(1,1,1)
		
		local Parachute_Decal = Instance.new("Decal", Parachute)
		Parachute_Decal.Texture = "http://www.roblox.com/asset/?id=18051314"
		
		local BodyVelocity2 = Instance.new("BodyVelocity", Parachute)
		BodyVelocity2.Velocity = Vector3.new(0, -20, 0)
		
		local BodyVelocity = Instance.new("BodyVelocity", RealParachute)
		BodyVelocity.Velocity = Vector3.new(0, 100000, 0)
		
		-- parachute welds
		local s = Instance.new("Weld") -- Real parachute weld
        s.Parent = char
        s.Part0 = RealParachute
        s.Part1 = Parachute
        s.C0 = CFrame.new(0, -15, 2)
		
		local w = Instance.new("Weld") 
        w.Parent = char
        w.Part0 = Parachute
        w.Part1 = char.Torso
        w.C0 = CFrame.new(0, 0, -1)

-- parachute's position 

	while true do
			local GroundLevel = (Parachute.Position - game.Workspace.Baseplate.Position).Magnitude
			print(math.floor(GroundLevel))
			
			local floor = math.floor(GroundLevel)
			
			if floor == 12 then
				print("STOP")
				RealParachute:Destroy()
				Parachute:Destroy()
			end
			wait(2)

		end

	end)
end)

It looks like you weld the parachute to the character and then give it BodyVelocity. This makes it a part of the character's system, moving character too.

It might be best to simply use a BodyForce to partially counter gravity.

Another option is to set the MaxForce of BodyVelocity to Vector3.new(0,[number],0) so only the Y axis is affected.
