BAC One-Eleven crash on test flight. Deep Stall

Company pressure

There was enormous commercial pressure on both the 111 and the 10 to perform as offered in the 'brochure', and as it happens the 111 was the machine that paid off commercially even after the initial problems, due to offering a quantum leap in jet travel for the emerging holiday markets. The 10 was designed to fit the BOAC routes not suitable for the 707 so rather like the Trident had a built in limitation 'commercially' for the world market against the USA.
Both machines ended up as a class act on their individual merits, however the 111* was better suited for 'stretches' as required where as the 10* gained rather an unfortunate reputation for fuel consumption v px load but was always popular with clients due to low noise levels and ride. BOAC killed off the 10 as the bean counters gave it the thumbs down, but as proved in the long run it required less maintenance than the 707 and the overall costs balanced out. Of course in the end it was easier to extend runway lengths at airports worldwide than build specific aircraft to suit old facilities. It so happens that at Newquay airport one can 'explore' both* these very British machines which were produced as the industry started its decline in that market. It is amazing that decades later commercial pressures saw us with the 737 max, certification fiasco which brings home the magnitude of what is at stake nowadays when you try to short circuit pax safety to sell machines.
