Vanguard acident LHR 27 Oct 1965
As a matter of interest, I was due to take BLEU Varsity 417 to LHR for fog flying that night. Unfortunately, during the pre-fog flying air test, the Elsan toilet at the rear of the aircraft broke loose and spilt its fluid all over the floor so the flight was cancelled.
Had we been there, that accident may never have happened - the usual RT chatter went something like "Whose that doing circuits and landings while we are holding?" "Its the Blind Landing Exerimental Unit" - "Diversion to Manchester please".
Also, the Vanguard and Viscount had the same VSI problem as the Canberra - the VSI initially went the oppopsite way to the nose of the aircraft i.e., lower the nose and it indicated a climb.
Sad that we spilt the Elsan that day.
