I DON'T THINK THE EXTENDED RUNWAY WOULD BE ANY PROBLEM FOR A LADEN 757 TO GET TO tHE CANARIES OR TURKEY, YEARS AGO FOLLOWING OVERHAUL BY ATC LASHAM OR HEAVYLIFT A CANADA3000 757 DEPARTED FROM SOUTHEND TO TORONTO DIRECT, ALBEIT WITH ONLY THE CREW ON BOARD, AND THAT WAS WITH THE RUNWAY AT 1605 METRES, AND IT DIDN'T TAKE MUCH MORE THAN HALF OF THAT TO GET AIRBORNE
THE ONLY PROBLEM I CAN SEE WOULD BE THE INFRASTRUCTURE AT SOUTHEND FOR HANDLING 757 PAX FLIGHTS
