I used to work at Southend Airport 1983-1986 and I can remember Hispania Caravelles heading out to Malaga non-stop, fully loaded, happily blasting the sandbank over the railway line and into back gardens whilst holding on the brakes for a runway 24 departure. However you couldn't quite see where they rotated, bet the roof tiles of the church got dislodged a few times! I think a 757 would be ok, no different to BY operating out of Southampton for a short flight to Palma a few years back.
