Narrative:
c/no.1042: DH.60G Moth [Gipsy I] registered as G-AAGS [C of R 1960] 23.4.29 to Malcolm Campbell (London) 1927 Ltd, Stag Lane, Edgware, Middlesex. C of A 1868 issued 30.4.29. Sold on and re-registered [C of R 2066] 20.6.29 to Samuel Perry Tyzack, Sywell, Northamptonshire

On 30.8.1933, Whilst being flown by Miss Ethel Doreen Tyzack (aged 26 at the time), a wing struck and killed Wilfred Allport, who was standing on a beach watching a regatta at Barmouth 30.8.33; Clifford Allport, standing next to Wilfred, was seriously injured. The Moth subsequently crashed into the Mawddach Estuary, off Barmouth Beach, Merionethshire, injuring Miss Tyzack. According to one source (see link #9):

"...she crashed whilst performing an aerobatic display in D.H. Moth G-AAGS in Barmouth, killing one spectator and injuring another. She suffered head injuries and severe shock. The inquest's verdict was 'accidental death following a judgement of error' on her part".

Miss Ethel Doreen Tyzack (b.16.9.1907) recovered from her injuries, married German-born Ronald Erwin Ottmar Velten in 1936 (they were still flying in 1952) and died aged 96 in January 2004 in Bournemouth, Hampshire.

Registration G-AAGS cancelled 12.33 due to "destruction or permanent withdrawal from use of aircraft"
