My only Javelin memories from the Tower at Tengah in 67 was the weekly incidents ... either the slipper tanks blowing off of startup, due to something to do with a starter vent being blocked, or the very agricultural u/c downlocks failing, leading to the Javelin sliding sideways off the runway.
Tower trainees were warned to expect a "Crash State One" on a weekly basis. Poor Javelins, they had had a hard life, and 64 and 60 with their Mk 9(R)s were the last in that distinguished line.
A fascinating beast - there was something about them that I simply 'liked'. I have no idea why ... perhaps it was their age?
