A government decision to build a third runway at Heathrow means the airport will only get much busier.
While the controversial decision might mean economic lift-off for Britain, it spells a period of turbulence for Theresa May as Prime Minister.
ITV News Political Editor Robert Peston reports:
Tory MPs are taking lumps out of each other on Heathrow, grammar schools and - above all - the true meaning of Brexit.
Environmentalist Goldsmith called the move "catastrophic" - and announced he will now stand as an independent in protest.
The expansion of the London airport will affect the whole of the UK, with more domestic routes, while impacting air fares and house prices.
