120m extension?!! Bringing the TORA upto 1949m, I would love to see what sort of long haul they are proposing with that pathetic improvement!
BAA, please stick to doing what you do best, build more over priced shops in the terminal, charge even more for your ridiculous parking or even continue to rip off the flying club with landing charges if that really does give your MD a 'semi', but please refrain from pretending that you know the slightest thing about public transport aircraft performance...
