A car, plane or whatever should only have one driver/pilot. Planes have dual controls by default but this sort of nonsense should not be allowed to happen. Thi

  In cases like this it's almost always some variation of normalization of deviance. If company culture doesn't strictly enforce callouts 100% of the time, it's easy to get into a routine of everything being just fine 100's of times until it isn't. Really these sorts of things show there should be a failsafe mechanism that provides tactile/haptic feedback to the pilots if the other inputs are "fighting" theirs. Even an audible alarm isn't enough, as you'll likely get more than a few of those during events where it matters. Proper CRM of course should make this "impossible" - but in high stress moments any more layers of swiss cheese you can add the better.

  Ever see those really long fire trucks? Two drivers

    But the second driver of a tiller truck only steers the rear wheels, more like the pilot of a glider being towed.

  Agreed. There should be a stick-shaker or similar to let pilots know the other control is being used. Maybe not the existing stick-shaker, since that's usually for stalls, but something similar. I have no idea why the pilot-monitoring would have taken his controls. Or why the pilot-flying wouldn't have called him out for it. Possibly a seniority issue - we've seen similar issues before. Hopefully the french aviation authorities can determine the root cause.
