From the morning paper:
The flight arrived at O'Hare about 1:45 p.m. and blew a tire as it touched down; the aircraft skidded off the side of the runway, leaving the main nose gear and the left main landing gear in some grass, according to Elizabeth Isham Cory, a spokeswoman for the Federal Aviation Administration.
