A quick check of Nav Box tells me Panshanger is 8.8nm 119 degrees from Luton, so a road journey of appx 12 miles i would have thought?(straight line plus 20% usually works out close enough) But surely the cost of two taxis and you might as well drop in at Luton and do some ILS pratice and mix it with the heavies

Also try giving the club a call,
