KETCHIKAN, Alaska (AP) — A mysterious liquid leaking on a cargo jet sent emergency responders to the island that is home to the Ketchikan, Alaska, airport.

Turns out, a bartender with a dish towel could have handled the problem.

The Ketchikan Daily News reports (http://bit.ly/1uLea7N) the leak Tuesday on the Alaska Airlines 737-700 was traced to a container of lime juice that broke open during a flight from Seattle.

Alaska Airlines spokesman Cole Cosgrove says workers first detected the sour-smelling liquid coming from a cargo container.

Airport staff took a cautious approach and called for emergency responders from the Ketchikan Fire Department to take a ferry to the airport on Gravina Island.

The leaking lime juice was diagnosed as the source at 7:30 p.m.

Ketchikan cargo was unloaded, and the jet continued to Sitka, Juneau and Anchorage.
