Quite agree, Mr Rainboe. This has done before, but the FAA is so twin-centric; no one knows how 4-engine planes should be operated so they just apply the rules they know. (the short-sighted, know nothing idea) OR the cynical version, why let those furriners get away 4-engine ops.
The AF rule within the transport types-the bombers could depart on non-combat missions with one out, I believe.
