Hi

You find there now reports about many planes like
Spitfire, Hurricane, Mosquito, Hellcat, Aircobra, Kingcobra, Mustang, me109, me262, minshell, 20mmshell, F2A-3, ...

P.S tripod is slow to access - if you see the headline of the directory, and nothing works anymore, try the stop-button - maybe the links show up then.
If you want to see a document, i recommend a right-click with the mouse and "save source" to watch it offline, and not in your browser. The download is usually fast.
