757 and T5
Could it be the days of hand luggage only are closer then we think.....
Seriously, whilst no 757 will be scheduled into T5, the 757 might have to stand in for a machine that has gone tech. My guess is that on those odd occasions, the luggage containers will have to wheeled up to the 757 and then unloaded by hand into the belly of the 757. Not really too different to what happens now with the baggage carts.
The same would apply to a 737.
