There’s some suspicion that it might have been RAF or army. Both have adventure bases close by…..
Can’t see that to be honest.
The quality of the MTB’s provided at MoD adventure training centres isn’t very high and I don’t believe, unless things have changed dramatically recently, the budget would stretch to decent night lights for 30 odd riders, nor would the very prohibitive procedures in place for allowing adventure training likely allow organised night riding.
Still, its interesting to see the military blamed for something other than murdering babies in Iraq.
Ps, I posted a link to this thread on the RAFCC site to let them know they are having the finger of suspicion waved at them by some Trotskyist.
