The Russians did unfortunately experience a deep stall with a Pulkovo Airlines Tu154 only a couple of years ago, over Ukraine, trying to climb up over a thunderstorm in the cruise. Classic deep stall result, coming down to the ground in an uncontrollable wings-level attitude. It's basic physics.
Meanwhile the UK experiences led to a requirement to fit stick pushers on T-tail aircraft, but the 727 was never so fitted so I wonder how much of the "sharing safety" atually happened. When the first UK-registered 727s came secondhand to Dan-Air, many years after their introduction, they had to be expensively modified to fit such a device.
