RW Caravans (Born Again)
It so happens that the Air Cadets (Gliding) eventually inherited some of these said caravans which was an amazing luxury compared to standing around in the freezing cold. They were used to 'Aldis' the winches for launching, plus performed a wonderful secondary duty of providing tea & buns and preventing hypothermia whilst waiting to be 'catapulted' skyward. It is a shame the 'vans' do not have serial numbers as (as this thread shows) they have a history every bit as interesting as the aircraft they looked after. Not Shure how they were kitted out when new (just a bare shell with greenhouse for us) but a gas cooker and a couple of batteries sufficed to do us proud. Our 'Boss' (always the inventor) actually made up a multi vane windmill out of dural sheet and coupled it up to a 12 volt generator to charge said batteries. This was mounted aloft on a suitable frame but had no speed control so if the wind got up it was 'interesting' and very noisy. The caravans allowed us to replace the 'Bat System' of winch signalling with a simple light control that used a green filter to send a slow flash for take up slack and then quick pulse's for 'All Out'. A steady Red indicated stop winching.
It was amazing how many 'bodies' could be crammed in the space available when it rained or snowed.
