I am glad to hear the F70s will be around a bit longer. they make a nice change in the skies . One came scooting over Camberley downwind for LHR (on easterlies) the other day-no doubt diverted from a busy Lambourne hold .
Made a different noise and different shape from the legions of 73s/320s/Triple7s etc etc which all look like 'same aircraft different height ' from below . Must be a bit boring being a spotter these days
