Never had that but I did have a generator driven by the engine from a Phantom jet. Fun part was that it used a three inch high pressure natural gas line instead of compressed air to spin the turbine for starting then exited thru the roof. The exhaust from engine had an extension that also exited the roof and it being large and strong the installer used the jet exhaust stack to support the gas exhaust pipe. Cutest thing you ever saw.
