This was looked at back in the 90’s as a proposed strategic airlifter for the RAF with RR RB211’s and Honeywell avionics suite. My dad was involved in the bid and worked for the UK arm of antonov airlines,despite my begging he didnt take me when he went on a jolly on the 225,124 or the AN22.... Great piece as always…

Sorry to correct you but the Sioux city DC10 did not use its number 2 engine for pitch control as the fan disk had disintegrated rupturing the hydraulic lines in the tail,only engs 1&3 were runners.
