But it's amazing how the wheel has turned full circle with the new air-driven drogue lights!
A chum tells me that the receiver pilots thought they were great - they did the trial in late evening and the drogue was superbly lit. Also the drogue aerodynamic behaviour was, if anything, better than the normal one! And it trailed and rewound very smoothly, with virtually no 'sucking spaghetti' effect.
I'm surprised that, as well as Mr Miller's dynamos, there wasn't a Sturmey Archer 3-speed lurking somewhere within the Valiant's Mk 16 HDU, Arters!
