HARRISBURG – A small plane made an emergency landing on the PA Turnpike Monday evening, shutting down some traffic and prompting a crash. Turnpike Commission spokesperson Carl Defebo said the single engine Cessna landed due to engine failure in the westbound lanes and then was struck by two tractor trailers. Two people in the aircraft were not hurt. The PA Turnpike tweeted shortly after 6:30 p.m. that some traffic was blocked between Lebanon-Lancaster Exit #266 and Harrisburg East Exit #247. The road was cleared a couple of hours later.
