Sywell isn't far from me as I fly out of Oxford and I've had occaison to nip over from time to time. The last time I went they were really friendly. My departure made me laugh though, as the ATC was bursting a blood vessel on the air with a pilot who was clearly not lisiting to her traffic requests. I decided any futher communication on my part would have added to the confusion so thought better of saying anything further. Generally though I think it's a nice place and I like it. The only critisim I have is it's attached to Northampton!
