Yes Beags, it is not a new idea. Back in 60 at 2FTS, Syreston, there were for a while four Kuwaiti Air Force Jet Provost camel-scarers lodge with us. The Kuwati studes (Jaguar saloon drivers to a man) flew with concrete headed rockets under the wings. The destructive powers of even these un-guided weapons was shown by the inadvertant release of a full salvo by one of the studes on the flight-line - the trees and largish earth-heap on the other side of the airfield didn't stand a chance! The spent missiles are probably still on the bottom of the river Trent (for those that don't know Syertson, river runs along the back boundry).
