The glaring omission from the list has to be a more contemporary type....
The A.T.P.
An accountants dream due to the fuel burn....however, accountants have no experience of maintenance or operations.
Each one lovingly hand crafted at Chadderton and Woodford in the vague hope the parts would fit all the aircraft built, reliability was never included in the design spec, let alone maintainability. The cabin door mechanism was a work of over complex art allied to the shoot bolts happily freezing after flight.
It was a truly inspirational idea to locate the airstairs external retraction button at the base of the fwd pax door and to have to subsequently have a mod.programe for access panels that should have been incorporated in the build.
Sitting at the back, watching the horizontal stab vibrate was always "interesting" as was watching your meal transit across the seat back table due to the aforementioned vibrations. A cheap and tacky interior only added to the pax experience.
There were several IFSD's in the initial phases including one for the Loganair delivery flight from Woodford to...MAN.
Such was it's success, Waste of Space were compelled to provide a "hearts and minds" campaign for the operators, free sandwiches etc and a look around Woodford with all the associated
PR verbal garbage in attendance.
The only plus point is that the type can be used as a classical example for future design engineers as to "how not to do it... and how to make a complete and utter debacle as a result if you do ".
