I thought this was interesting when I saw it as a breaking news alert last night on a local news station in San Diego.
Around 6:00pm on Wednesday night, the FedEx DC-10 (or MD-11, sorry I'm a newbie) arrived into San Diego and was taxing to its parking on the east side of the airport. While making a left turn to cross the runway apparently the airplane was stuck. Part of the plane was on the runway and several flights had to do go arounds while they towed the plane off the runway. The reported had said “the aircraft was on part of the taxiway that didn’t support its weight” It was about a 20 minute delay. Couldn’t find pictures or articles on this story but maybe someone can shed some light?
