Air traffic over Wellingborugh.

Hello all.

Does anyone know what jets fly over Wellingborough? I work there and hear jets almost daily. Sywell is near by (we hear the Blades a lot) and Luton is to the south. I’m fairly sure it is not civilian traffic. I’ve lived up here 18 months and have never seen an airliner overflying the area.

I presume it is military traffic as they sound fast and the odd EH-101 (and UH-1) come along low level.

Thanks in advance.
