The Tiger Club at Headcorn has a DH82A Tiger Moth G-ACDC which is used for, among other things, trial flights (i.e.jollies) for members of the public. It is all done on a public transport CofA and is therefore a commercial operation. I fly these trips now and then and its great fun, the punters love it!!
G-ACDC was built in 1933.
If anyone can beat that, I'll eat my hat!
