At long last an initial decision has been taken and the consultation, planning, then no doubt the legal objections can commence.
A couple of facts I learned today was 1) Heathrow is the busiest two-runway airport in the world (other airports have three or four, Schiphol actually has six) and 2) Gatwick is the busiest one-runway runway in the world (actually has two but one is never used unless the first runway is put out of commission for repairs etc.).
