On 18 July 1971, a Pan American Airways Boeing 747 was cleared to land on Runway 25 at Sydney (Kingsford-Smith) Airport. The T-VASIS was operational but the crew was unaware of its installation and didn't know how to use it. The aircraft crossed the 25 threshold at a wheel height of 123 feet and after a long float touched down 4000 feet beyond the 25 threshold.
There was no evidence of braking marks until the aircraft had travelled a distance of 2,181 feet beyond main wheel touch-down. The aircraft overran the runway and after turning 37 degrees to the right, became bogged in soft ground with its nose-wheel 325 feet beyond the end of the runway.
A transcript of the CVR revealed the co-pilot saying at 5 miles on final "Hell of a place for a graveyard...prime real estate" and minutes later "Could be it's that foreign kind of VASIS..shows too high, I guess."
Here is the DCA Incident Investigation Report and it is worth reading.
