Balmy: It can indeed happen... I believe spatial disorientation was the cause of Sharm El Sheick's crash a few years back. Not saying it's the cause here, though.
Autoflight: Hmm... It sounds like we flew for the same African operators...
Good description! I would hope though that a reputable airline like Kenyan would have better practices than this... Even though anybody can be badly loaded without it even showing on the loadsheet... It wouldn't be the first time on the continent that an airplane takes off way overloaded without the pilots even knowing about it...
Anyways, who knows what happened...
