Think the nicknames sum them up well
The 10 was known as the death ship and MD 11 - mega death two...
Crap systems design - non locking slats, no protection with loss of hydraulics and the lines routed around engine two and exposed in the landing gear bay.
We were only allowed to operate through the CWS - manual flying banned because two many of the older guys buggared up landings... And as for the noise in the cockpit still suffering with tinnitus.
Besides the above and that our American cousins wouldn't fly with is it was a great aeroplane if flown properly.
Did a visual from 12grand downwind on my only trip to Caracas - spooled the engines up at 700 ft.... Pure delight.
