Well done, I thought this thread had died!
Is that Rolf Harris in the Right hand seat????
Not ATC, but I hope relevant. Here is BGA 668, the week I went solo. in this a/c at Portmoak in 1976. Sadly this a/c was damaged and used for spares at Upwood in 1985.
and BGA869, in front of Bishop Hill, Portmoak 1976. This T21 is evidently now in Delmenhorst, Germany awaiting restoration.
