Re-Inventing the Wheel
Here we go again re-inventing the wheel. Back in the bad old Cold War days the PI (now Int) Branch had a recognition materials cell at JARIC (now long gone). They used to produce cards and books on a comprehensive range of land, sea and air equipments that were available for free to users. The maritime ones included pictures of ships and submarines from all angles, including above. Some of these survive in the Medmenham archive at Wyton. Note top self: do we offer these documents for free to the new generation of P8 crews or flog them at large cost to the approved MoD contractor? Why don't some people ask around before putting out a tender?
