Seats are for inside
Not sat up there on the wing.
More courage than sense.

On a recent holiday we were passing an airfield when we spotted a plane on the ground, and someone clambering up on top of the wings. We waited, and watched, as the plane took off and performed aerobatics with a brave soul strapped to an outside seat. I now have a granddaughter who wants to do wing walking and sky diving! Nutters.
