Funny direction this thread has gone
I've 3k hrs on 737's, and wasn't really asking whether what they did was correct or not. I heard them on freq, and the declared a mayday. Do what you want, I don't suppose Spanish ATC even know what a Pan call is, so bang in a Mayday to get their attention.
My questions where, whats is this particular aircraft like on one engine, and does anyone know how they got on?
I don't make a habit of questioning the choices pilots make in a situation I am not in. All I know is that I was happier in the cockpit of a 737NG with both engines running, then sat where they were sitting at the time.
