Sloooooooooooooooooowdown peeps. Could be a crew calculated take-off problem, nah? Me, I'm sure it's load and balance from JNB. The loadsheet checking procedure on EK, I have been told, is almost foolproof now. Regarding checking the loadsheet, you may as the crew check it all you like but if its wrong compared to the loadsheet, there is nothing you can do about it except be extreme professionals and save everyones lives. Well done EK pilots.
