Airport Fixes Sticky Problem on Runway

The sticky resin that grounded about 20 planes at Milan’s Malpensa airport has been cleared from the runway and flights are back on schedule, airport officials said. One of the airport’s two runways was closed Thursday after officials discovered that a resin applied overnight had melted and was sticking to the wheels of aircraft that landed or were trying to take off. The resin was applied to make the runways more visible to pilots. The head of the company that runs the airport blamed workers that had been subcontracted for the job and said he would report the incident to authorities. Problems have occurred at the newly revamped Malpensa hub since it opened Oct. 25.
