15 T42Bs were built making 17 Eagles in all. 8 including the prototype BGA 722 (mid air collision with a Sky at Lasham 14th June 1958) have been written off. 8 of the remaining 9 are accounted for:
- BGA 740 is the second prototype, the St Yan world championship winner, and is sited at Pocklington where it is flyable. This aircraft, Comp No 11, was at Lasham for many years and was known as the “Beagle”, which translates as “Blue Eagle” because of its colour scheme at the time. The author was part of the syndicate for a few years and never knew the provenance of what he was flying!
- BGA 780 is at Hinton-on-the-Hedges and needs restoration. This glider was originally owned by Peter Scott.
- BGA 787 (ZK-GBG) stored in New Zealand (Said by David Williams of the Odiham Kestrel Club, THE expert on Eagles, to be not far from flyable).
- BGA 825 has been restored by David Williams and is flyable at Odiham. This aircraft used to be owned by Wally Kahn and at the time had competition number 4.
- BGA 828 (BBB), flying at North Hill.
- BGA 830, stored at Keevil. This is owned by Dave Williams and is awaiting restoration.
- BGA 841 (BBQ), flying at Millfield though (Feb 2014) believed now sold.
- BGA 849 (ZS-GDP). This is the “my stery” Eagle, likely no longer in existence.
- BGA 880, owned by Gordon McDonald at Lasham and is airworthy. This was the original Imperial College No 96 which was the IC training machine for so many years.
