So how many Boeing aircraft have had successful conversion programs? Well, the 72,3,4(Classic and -400),5,& 67 - count them, 7
I think it is a bit unfair to compare Boeing's history and heritage to Airbus which is a relatively new company in comparison. So it isn't any surprise that Airbus do not have the same number of freighter converted aircraft; Boeing have produced so many more airliners in their history. Also, planes aren't built the way they used to. Planes like the 707, 727, DC8 etc were built like brick sh*thouses and perfect for the rough world of freight especially when ending up in African or South American operations. I would be surprised if even Boeing's future aircraft such as the 787 will be capable of such things and in fact with the carbon fuselage, who knows whether they will even be able to cut a freight door in it to make a BCF!
