Suppose your lucky it could have came through the window.
Taxi dirver who lives opposite me said he was coming back from Teeside airport on the A19 @ Easington services with a fare in and 2 young lads dropped a few bricks off the top of the bridge and one went through the back window. Said there was a loud bang and glass everywhere.
Took the fare home with no back window in. Put him out of service for the rest of the night. Could have been worse if it hit the roof!
Need to be taught a lesson!
