Paint: I remember when 74 Sqn celebrated their escape from fin-painting rules at the time of the creation of STC ... as there was no extant order preventing it. Accordingly, the following morning 74’s line at Tengah sported a handful of Black-Fin Lighnings.
Within 2 days, most of the paint had gone from the fin leading edges rearwards, creating a slightly tatty appearance. The problem was subsequently resolved, somehow!
