An airplane mishap at Des Moines International Airport was less than met the eye this morning. Airport spokesman Michael Audino says it happened about 7-30 in the morning. A Boeing 727 cargo plane inbound from Milwaukee landed safely but didn’t make a turn on the taxiway and wound up with a couple wheels in the mud. The main runway closed for a while as crews dragged the plane out of the mud, but airport operations continued.Nobody was injured, and the airport remained open though the runway closed for a while. If it hadn’t been a cargo plane, the 727 could have carried about 100 passengers.
