flying freight in a DC9,you better believe i'm wearing a leather jacket,started wearing one when i flew the 3,its a tie in to our ancient,and honorable round engined past,not just open cockpit,and if you are overcoming gravity,and drag for a living you are not a poseur,you are one of the brothers and sisters who are 1/2 crazy enough to put it on the line day in and day out for this profession when they could be warm,safe,but not quite alive in some cubicle, if you are a CFI, or a 10k hour ATP, you rate it. IMHO.
