With all the aggro etc about building a 3rd runway at Heathrow Airport got me having a crazy idea.
How about instead of building more runways, across from each other, the runways themselves were built on top of each other, multi-storey car park style with a slip road down to ground level from each runway.
I was thinking of each level being 500 ft above the last one and being 1,000 ft across to aid clearance and take off and landing of the biggest jets especially now with all landing devices afforded to passenger jets, that they could land themselves.
Crazy idea I know, so would it work?
