RE: Online Website to tick off a/c?

A web site giving this service would be very rare and I’m sure you’d have to pay for it, I don’t know of any.

However I know of a computer database program called No More Underlining which works on your computer. Very good program, you can tick aircraft you’ve seen, photographed and it contains all of the info such as Previousd regs and construction numbers which you can easily search and find.
