Dennis,
Brendan is still around and the Enstrom was G-BAHU which became
EI-BDF. I think BDF was either owned by or sold to Barry Sheene. My good friend Colin Sayers (RIP) came over to Ireland to teach Brendan to fly and ended up staying becoming chief piot with Irish Airwork and then to Irish Helicopters. Brendan then graduated to G-BAKX,EI-BHI, and the replaced that with an Agusta 109 EI-BUX.
