Pilot by a very short head from Flyer...
I was expecting terrible things of the new editor of Pilot. I was wrong. It's still number one.
Flyer (which used to be edited by the same chap and was then pretty so-so - work that one out) is now pushing it EVER so hard; brilliant range of contributors (top? John Farley - I read his stuff a sentence at a time, closing the mag in between; you simply can't hurry it).
Third - honourable third - Today's Pilot. Their diary last year was a fantastic idea, I still use mine.
Coming up fast on the outside - General Aviation, AOPA's mag. Quality shot up a little while ago and the editorial is concentrated and high-quality.
Still mystified as why Pilot would get slagged.
