excuse me if this has been asked before but would it be possible to have passenger loading to be able to walk out or in gates/doors at airports instead of the bus as an option for example Luton EGGW and gold coast Australia people walk out to and in from the planes stairways. i would also like to see the option of de-icing at special pads as like EDDM. also de-icing trucks have to do this from the front of the wings not the back.Colin
