xtypeman, your idea would work best using NHT, if it is ever going to open to small scale scheduled operations (and do NOT mean as a third LHR rwy!). Also leisure travellers should be catered for as well as business travellers.
Provided a station is provided adjacant to a NHT terminal, it could be 17 minutes to the west end (Marylebone) and a coach to LHR is just a 6 mi. ride.
PlymSpotter, what is happening at NHT?
