Reason: A couple of years ago a crew took off from an ice covered runway with the parking brake set. They did not realise this mistake during takeoff, as the acceleration appeared to be 'normal'. However, they found out when landing at the destination... Or so I was told.
They found out when they failed to make enough speed to get airborne, after calling V1, and crashed off the end of the runway. 46 passengers (of 219) and one cabin crew member died.

It was a DC-8-63CF on November 27, 1970 on runway 06R at Anchorage, Alaska (Capitol International Airways supplying a charter for the US Military Air Lift Command). Power was set on the icy runway, acceleration was initially normal (with the low sliding co-efficient of friction).

After the initial acceleration the heat began to damage the tyres. The first scrap of reverted rubber was found 170 meters along the take off run, tyres were scrubbed to the chords by 820 meters, at 1300 meters all of the port tyres were blown out and all starboard tyres by 2650 meters. All wheels were found ground down to the hub in only one place.

This accident is the reason that "park brake" was added to the config warning list (it wasn't on the list when I started flying).
