Polite notice: The contact details below are not for Northampton/Sywell ATC, they are for the operators of this website. You'd be surprised by how many calls and emails we get requesting clearance to fly a drone in a FRZ! I'm afraid we can't help with that, you'll have to contact ATC direct. We honestly don't have any additional contact information for Northampton/Sywell; everything we have is published above.
