I recall that at Townsville in the 1960's I think, Distance to Run markers for Runway01 were set up on the flight strip. . I believe these were for the use of visiting USAF B66 twin engine jet bombers. If a certain airspeed wasn't reached by the time the aircraft was passing a specific marker i.e 100 knots by the 4000 ft marker, the pilot would abort the take off.
In fact I witnessed that happen when we watched a B66 start his take-off roll only to abort around the time it had passed the 3000 ft marker. The pilot taxied back and tried another go but this time kept going and climbed away normally. Of course we didn't know the real cause of the first abort or whether he hadn't reached the minimum required speed by the time it had reached the 3000 ft marker. Some weeks later the distance-to- go marker boards were taken down and to my knowledge never used again.
