Hey, and thanks 8_. I retired my zoom bags 20 years ago. I didn't have an O2 mask on my bucket or in our AC when I wore gold wings. My current job now (2 feet on the ground with no naval aircraft strapped on my back) has me at 6k feet alttitude. If my memory, math and situational awareness serve me right, thats 5500ft higher then all but maybe 75 hours of all my logable flight time. Yup, Dilbert does not need O2 at the alttitude he's driving his SPAD at for nape scrapes, dodging banana trees and other purposes that make us chose this AC. As this post started, Dilbert (and charlie lima) is behind the skill and knowledge curve. Yah I'm yammerring and you are way correct and on topic. Dilbert should be boring holes in the lovely south east asian sky with a brain bucket and no O2 mask. That is my goal. We can take Dilbert behind the line shack again and again until he get's his sierra in one sock. There is a whole ready room of SPAD drivers looking forward to your help here. Rest in peace Buck Owens:ph34r:V/R, CL
