Airlines' Long Term Technology Investments

Airlines like to hang on to investments for a long time.  Take the MD-80 as an example or that US Airways just retired their last 767-200 after 25 years of service.  They are also the only industry clinging to perforated paper printers, the highlight of mid 1980's technology.  Luckily airlines can order paper and ink on the internet or these printers would be in the trash next to floppy disks and Zip drives.
