Hairy, I take my Panama hat off to you sir. That limbo flying looks an 'interesting' proposition, and you almost got several of the balloons - it's just that they didn't burst.
Long may your delightful aircraft continue to age. BTW, with all your flying do you get Hair Miles?
The oldest machine I've flown is the Tiger Club Moth G-ACDC, though I believe there is some debate as to exactly which bit is original (if any!). Otherwise it is the Grace Spitfire ML407, built in 1944 - I've got 37 minutes on that.
