CHICAGO (CBS SF) -- A United flight from San Francisco to Chicago skidded off the runway while landing at O'Hare airport Friday morning.
Flight 734 landed just before 10 a.m. PST Friday.
Video showed snow on the ground, but it was not clear if weather played a role.
No passengers were injured and there was no word so far if they had to evacuate or were still on the plane.
Passenger Don Dodge posted photos on Twitter just after the plane came to a halt in the snow off of the runway.
Emergency vehicles were visible in the photos arriving at the end of the snowy runway.
Last month, a United flight from Seattle also skidded off the runway during a snow storm
for more features.
