The Federal Aviation Authority in the US apparently follows no
such tenant. I was apalled at what I uncovered when looking
into the 2004 air traffic control outage(*). Apparently the
"Voice Switching and Control System" linking pilots to controllers
on the ground was "upgraded"(+) from a control subsystem using
Tandem Himalaya Non-Stop computers to Microsoft Windows 2000.
