'Needle threading its way through the cloth of the sky' might have come from the pen of Aiglet artiste par excellence and self-proclaimed 'Scotland's' Greatest Poet' the late Ranald Porteus himself, but is doesn't make it as an explanation for the name. As originally built, the J/1B Aiglet was intended as an agricultural aircraft, not an aerbatic mount, and was virtually identical to the later J/1N Alpha. The Aiglet Trainer, which came along a year later and was based on the J/5 airframe, was the aerobat, but by then the name was already in use. A pint seems to be the best solution, and one that RP would certainly have approved!
