Hey Mike !!!
Don't take any of this as "CRITICISM" . Call it a CDR "Critical Design Review", we never had the PDR (Preliminary). But having worked with the aircraft companies for many years, you really don't want to have a "thin skin" going through a Design Review Cycle !!! But then, thats the REASON airplanes rarely just FALL OUT OF THE SKY !!!!
Good, Luck .... All will be just fine !!!!
Thanks, Lee
