As an aviation enthusiast of many a decade I can tell you that this sort of hobby evolves over the years. Back in the 1980’s the only tools I had were a pair of binoculars, a copy of Ian Allan’s abc Military Aircraft Markings, a note book and pencil. As time went on I added a 35mm SLR (remember those?) and a collection of high powered lenses. The 90’s saw the addition of my first scanner plus a spotting scope for good measure. I was pretty much sorted – not much got past me at my local airfield.
