Interesting trail we are following here chaps. I rather suspect that the trials and tribulations you suffered during your exploits led to the "tarmac underbelly" we had on the SF frames, by GW1. I must say, having experienced strips various at that time, the protection was very effective, the only problem we ever had was a double puncture on the RH mainwheels on a shale strip. Now, that was a story of fine flying and crew collaboration that might be relevant after Africa is done. Meanwhile, some great detail chaps, right down to the stowed GE hammock AA62. Keep it going.
