This was the scene coming up to the site of a bus crash on I-270. One of the most unusual crashes I have ever covered: the 26 passenger commercial bus, from Wolf's Bus Lines of York Springs, PA crashed through the guardrail of the NB HOV lanes on I-270 flyover, rolled, traveling down a 45-ft embankment, came to rest--upright--on jersey barrier. 12 were on board including driver. Driver Joseph A. Clabaugh, of Hanover PA was killed, but all others survived. Passengers were parents and children: the kids from Carlisle PA were home-schooled and this was their field trip to DC.
