Scooby-Doo #53

In "Fight or Flight!", the Mystery Inc. gang finds themselves on a flight plagued by mysterious ball-lightning strikes that leave behind a baffling mystery: every time the lightning hits, all the valuables carried by passengers disappear without a trace. With the skies crackling and the clues flying, Jo and the gang must unravel the electrifying truth before the next strike—and the next lost treasure—lights up the cockpit.
