On 14 May 1982, I did a night trial in an F-4 from Wattisham with a Harrier whose pilot was doing an NVG trial. Very late at night, so really dark - he spotted us very easily and read the registration no. XV404 very easily, with all our lights out.
Then he asked me to put an engine into A/B.... Immediately there was a brief call of 'knock it off' as it had virtually destroyed either his night vision or the NVGs!
