Sir Howard Davies: New airport report has 'more detail'

All three short-listed plans for a new runway in south east England will cost substantially more than the bidders claim, according to a report published by the Airports Commission.

Of the three proposals, one involves a new runway at Gatwick airport, and the other two suggest expanding Heathrow instead.

Explaining how the report was made, Airports Commission Chairman Sir Howard Davies said that they set out a number of future scenarios to try and "tease out" how robust the different airport models will be in different states of the world.
