All--

I expanded my search for a plane to include 152's today. I noticed something odd that maybe someone can explain. Of the 150 and 152 airplanes that are listed on the internet for sale, the 152's seem to have a much higher TTAF. Is there some explanation for this that I am missing?

Thanks,

John
