6 aircraft, 4 destinations. Lets face it, even if they were lucky to convert 10% of prudent businessmen to helicopter, shuttles, that is still not exactly a massive influx is it! And, oh, yes, the Olympics. Well, that would increase traffic for what, 4 weeks in 2012?
No, I wish Silverjet all the best and will probably use them at some time, but dreams of networks of helicopter shuttles are just that - Dreams !!
