10 years is a complete joke.
MAN's terminal rebuild will be completed section by section each of which will open in turn upon completion. Ten years is only the projected timescale from start of the first phase to completion of the final phase of the project. Given the scale of the project, the planning required and the need for the airport to remain fully operational throughout, why is this timescale 'a complete joke?'
