Currently these pictures of a damaged CRJ-200 are making the rounds on the Internet. Unlike said in many forums and blogs, this damage was NOT caused by a lightning strike! Instead it was simply caused by a cockpit fire, probably due to an overheated electrical power relay.
Preliminary NTSB report:
ASA Airlines flight 5533, a Bombardier CRJ-200 – registration: N830AS, experienced a cockpit fire on the ground shortly after external power was applied to the airplane in preparation for flight. The captain and one flight attendant evacuated the airplane via an airstair without injuries. They were the only individuals on the airplane at the time. The fire department extinguished the fire after it had burned an approximate 18 inch hole through the left upper cockpit crown skin. The flight was to be flown from Tallahassee Regional Airport (TLH), Tallahassee, Florida, to Hartsfield Jackson Atlanta International Airport (ATL), Atlanta, Georgia.
