STANDTO,
I don't know how long the Ronaldsway runway is, but the 757 is exceptionally powerful, and has amazing braking capacity.
An empty aircraft, full brakes landing gets in most places. 5000' runway at Skiathos springs to mind.......
As for an empty plane, full chat,brakes on until stabilised engines takeoff.......will probably lift off by the 1000' markers (well not quite, but you get the picture!)
Only problem is, the fridge won't be big enough on a 757 in charter fit!
