As well as opening the doors I also advocate throwing out all baggage (less mass = less for the brakes to do). Also my pilot's case, which I always tie to my left leg with 10 feet of para-cord prior to take-off. This acts as an effective ground hook. With the other spare hand I intend to dial 999 on my mobile phone as it's quicker than expecting ATC to contact the fire section. As 999 may take some dialling I have re-programmed it as 0000001 (or was it 00000001?).
Yes, of course I am joking. You don't think I would seriously throw out all MY baggage do you? Some of it is Italian leather!
