Lots of things towed up to Odiham, a Puma from Micheldever to Odiham, using a tow bar and a Landrover is one I remember..
It does seem strange not to assemble and fly them from Brize, after all there will be more coming. The Chinny's were done at the docks before flying to Odiham, and bar the odd bit falling off, it was successful (forward port emergency cabin window assy, over I think Southampton)
