All the local press and news here in the Midlands is reporting a new runway at BHX, the current site is restricted with the A45 to the South and the West Coast Mainline to the North.
However, the airport management have been very quite on an extension to the current runway (15/33) which is 8600', building a brand new runway maybe more cost effective, but would probably mean diverting or tunneling under the A45 either way.
There has also been talk of a brand new airport to the East of Coventry alongside the M45, it would effectively be London's 4th airport, with excellent transport links M1/M6/M45 and the West Coast Mainline all close.
The report is due to be published in three weeks.
