How can I move party very fast?

Hello ScriptingHelpers community! I want to do an Airstrike in ROBLOX so I need a Jet that moves. I tried this:

local Jet = workspace.Jet
for i=1,3000 do
for i = 1,1000 do
Jet.Part.CFrame = CFrame.new(workspace.Jet.Part.CFrame.X,Jet.Part.CFrame.Y,Jet.Part.CFrame.Z + 0.01)
wait(0.0001) 
end
end

BUT: I can't wait so short. Now is my question: How can I move my Jet very fast?
