Helicoptor landing in airfield car park.

[Mitzi.]

I was doing my 'usual' taking disabled adults on a day out, to a S.E. airfield, when to my surprise a small helicoptor landed bout 50 metres away, in the grass car park. Seemed strange to me as what seemed a perfectably serviciable airfield lied beyond the boundary fence. Helicoptor let some passengers out then after a few mins took of again. My question is... landing regulations for helicoptors....If it looks safe to the pilot ???

I add at no time did it look to me(on this occasion) that safety was comprimised, although visiting this airfield frequently it seems that kids, dogs, etc run pretty freely, in the car park.
