How lamentable that some folk find more satisfaction in attacking someone asking a legitimate question, rather than answering it, or saying nothing if they have nothing positive to contribute.
Some probably log in using a new alternative username when doing so, which would explain why someone has a ready recollection of posts made months before they supposedly registered.
For the OP, Cymmon - both Tiger Moths mentioned use Netherthorpe airfield, albeit the all yellow one far less frequently than the camouflaged example.
