Napolitano Eyes Tighter Security for Trains, Ships, Mass Transit - FoxNews.com
A VFT will result in the same security delays as flying except a stop in AY no doubt and the fact that its over an hour longer travel time.
Not to mention the glaringly obvious risk involved with travelling 300+km/h along the ground for 3 hours. A train crash at 300 or a plane crash at 300 is a crash at 300 and chances of surviving are next to nil. At least in a plane you're only close to obstacles for 30mins of travel time, regardless of distance.
