I had a look under Chambre de Commerce since many airfields are run by the local CC.

Here’s a bit about the Tour de France ULM 2008 using Niort as a destination. It mentions one Stephane Sylvain as being ‘responsable de l’aerodrome’ and a phone number for information: 06 1659 2302. If anyone knows, then he should!

Hope this helps.

Many thanks for the suggestion and contact details. I’ll give the man a call and hope that he can tell me more than has been the case with the others, on site, to whom I have spoken. So watch this space!

p.s. Niort was actually the start and finish airfield for last year’s ULM tour!
