Early this morning Japan Airlines announced that a Boeing 777 bound for San Francisco returned to Tokyo hours after taking off because the cockpit's warning light flashed alerting the pilots that the hydraulic level was too low.
The plane, which was carrying 236 passengers and 13 crew members, reportedly left Tokyo's Haneda airport about midnight and turned around four hours later, just to be on the safe side.
Passengers -- perhaps frustrated yet thankful -- hopped another plane that arrived safely in San Francisco this morning.
Meanwhile back in Tokyo, the airline told ABC News that mechanics had found a leak in the hydraulic system of the plane.
Tuesday's flight inconvenience happened just three days after an Asiana Airline jetliner made a crash landing at San Francisco International Airport, killing two teens and injuring dozens more. The cause of the crash is still being investigated, however, authorities say the pilot was flying the plane too slowly right before it crashed.
