The Javelins that I'd really like to see much more of, are the exotic RAE aircraft. The famous red and white FAW9 XH897 was photographed beautifully whilst in service but the photos seem to have disappeared without trace - I last saw them in Adrian Balch's "Testing Colours" book. Then of course there's the beautiful flourescent orange XA778. A top class photo was taken of this machine by Glosters, on roll-out, but I haven't seen the photo for many years (I think it was in an issue of "Air Inernational" many years back).
Even more obscure was the other RAE machine (the serial escapes me at the moment) which was painted mostly white, with various other colours applied at different times. Never, ever see photos of this aircraft
