Flyer/Pilot - difficult one. Always used to be pilot, but now it's looking a bit more like Flyer. Then again. I used to be indecisive, but now I'm not so sure...
Pilot have improved their site: <a href="http://www.pilotweb.co.uk/" target="_blank">http://www.pilotweb.co.uk/</a> and Flyer <a href="http://www.flyer.co.uk" target="_blank">http://www.flyer.co.uk</a> is just as good.
The US ones are all aimed, as someone said above, at the TC IFR lot - not us lower down the scale!!
