if 236 BAC 1-11 are "a total failure", Iwonder what consititutes a success.
I read somewhere that 1-11s were designed and manufactured for use in Europe and where corrosion-proofed to cope with the conditions. An inspection of a B737 & 1-11 of identical ages woulds reveal that the 737 would require extensive re-skinning due to condensation whereas the 1-11 might require a flick over with a duster.
