SCADA systems online, and a horror story about a non-airgapped Boeing 747 engine management system
747's are big flying Unix hosts. At the time, the engine management system on this particular airline was Solaris based. The patching was well behind and they used telnet as SSH broke the menus and the budget did not extend to fixing this. The engineers could actually access the engine management system of a 747 in route. If issues are noted, they can re-tune the engine in air.

The issue here is that all that separated the engine control systems and the open network was NAT based filters. There were (and as far as I know this is true today), no extrusion controls. They filter incoming traffic, but all outgoing traffic is allowed.
