I know someone who took out a runway edge light on departure but decided to continue with the flight to home base.
On landing he discovered rather too late there was a brake problem and the aircraft departed the left side of the runway, skidded across the grass and came rather close to hitting a light trainer carrying out engine checks on the "lazy link" prior to departure. Had the pilot of this second aircraft not been alert and taken off across the taxyway and across the grass parallel to the runway in use (!) there might have very serious consequences.
The aircraft was a red Hawk with white stripes.....no names mentioned but there are quite few identical ones!
