Funny you should mention the 146.
My one and only interaction with Mr Farley was in a thread many years ago questioning why a VTOL airliner never got beyond the Dornier attempt. I put forward the idea of a 146 with four Pegasus instead of the hairdriers it normally has.
"Engine failure during the hover" said Mr Farley "would be a bit tricky to get past the regulator" or words to that effect.
Succinct and to the point.
