A couple of years ago I wanted to do some businesss with a firm based at Sywell. I happened to be in the area one day so I decided to pay them a visit. After spending about 30 minutes trying every possible access route in that I could see, I tried to phone them. Their number was engaged constantly, so in the end I just gave up and went away. I rate the site as the most customer unfriendly that I have ever come across. What on earth do they think have they got in there? The UK gold reserves? I have never met another GA field that remotely approaches this level of security.
A few months ago I actually managed to penetrate the outer defences by following somebody in who knew the magic passwords. I agree that once you get in, the place is excellent and the facilities superb. But how many prospective customers get put off by the ramparts? A lot more than the inhabitants think.
