Delta/NW Confirmation
Just received this from friend, Rafael, appended to the NW pilot's email:
"Rafael, I just drove a Boeing 747-400 through this same area on the same day. We were circumnavigating a typhoon. The old timers at United taught us young kids to operate the radar in max gain at high altitude to avoid dry tops. I ended up at FL410 and due to strong down drafts we required max power to hold on to our airspeed. Lots of zig zagging, but not one drop of visible moisture. Fly fast, H."
This is factual; I remember H. when he was a kid at our local airport. His Dad retired from UAL as Capt on the -400.
