Boeing 747s receive software updates over floppy disks
i'm surprised that people are surprised by this.i work for aerospace, and this is fairly typical -- albeit not floppy disk examples, but we keep a bunch of old laptops running win 7 and other examples around, hound around for them and spare parts.  these machines are off the network, etc.these systems were developed 20+ years ago and per contract the a manufacture is obligated to maintain them for the service life, so unless these are obsoleted these are to last 20-30+ years.the costs associated of porting all tools from win 7 to a newer system and re-verifying 50K+ test cases to do a similarity analysis run into astronomical in terms of $ and months (years) of work.  no one really wants to poke that bear so you have situations like these.
