Hi Tonks!
Sorry, mate - I've been away on business for the last couple of weeks.
As far as I'm aware, the buffeting and stress on the tailplane were the cause of having the reversers deleted from the Standard VC10. Some Supers retained theirs for a while, but ultimately all VC10s in BOAC/ba/ service had but 2 reversers. But perhaps Lucy, her dad or her grandad could advise you further? BTW, she captained the last ever ex-airline Standard VC10 flight into St Athan on 27 Mar 01 when we took 142 to the knacker's yard - after I'd done a flyby at Filton to commemorate Trubby Trubshaw. The ac landed at St Athan fully serviceable, of course! Mind you, 142 lost#1 engine on me on 17 Jan 01, then #2 on 2 Mar 01, so perhaps she was trying to tell the RAF something by eating 2 Conways so close to her retirement date!
No RAF VC10 ever had 4 reversers.
Mars for Christmas - how I wish. Anything to get away from the ruddy adverts on TV.
