I thought it might give some modern aviators a laugh.
This modern aviator remembers flying beam approaches. Tern Hill in 1961.
What did give me a laugh was one 'I know it all' modern aviator informing another that the Ns were heard in one earphone and the As in the other. As neither of them weren't going to experience it I let it go.
Your'e doing a grand job cliffnemo, keep it up.
