I knew just two spotters and they did not conform to the stereotype. One was a Lightning/ Hunter mate and bucket and spade captain, the other was a TP (from VC10 days) including every Uk built Jag and most Uk built Tonkas. Flew with the latter to Schipol on company bizjet and with six hours to kill before taking our pax back home went Dutchmil spotting (nice warm day and better than kipping) The Dutch spotters were dumbfounded when they discovered his pedigree (they quizzed him because he looked like the police!).
So next time you get airborne, look a little bit deeper at your captain, you never know
