All Nippon Airways (ANA) Flight 175 from LAX to Tokyo turned around four hours into its journey after a passenger was found to be on the wrong plane. Supermodel Chrissy Teigen live-tweeted the eight-hour "boomerang" flight. Skeptics question the official story, suggesting the turnaround may have been due to a fuel imbalance or a government security test rather than a simple boarding pass error.
