Don’t think this is far fetched but what are the prospects of Stobart buying the golf course, kicking out the golfers and building a second terminal just south of Rockford Station and using that station as the station for T2? Also west of the golf course and north of the airport are farmers fields for an even bigger airport.
If Luton is planning to build a second terminal on one of the towns biggest parks, which has county wildlife status, nothing is safe these days.
