All the news about the last 747 being delivered made me think someone should start a pool about what will be the last one flying. Maybe they'll be like the dc-3 and the b-52 and live forever with some updated powerplants along the way? I'm betting the last one will outlive me unless the environmentalists shut them down. Another question is, what's the replacement? I assume Atlas, FedEx, UPS, etc. will want some new freighters at some point. What will they be?
