I suspect there is lots of very ancient software still in use in the airline and other major companies
Software and applications written before the IBM 360 ( mid 1960s ) was still in use around the world in 2000 and I suspect is still in use.
Manpower must still be available and to maintain them.
It is obviously very very expensive and significant risk to just swop over to a new system.
Obviously the press and MPs like the story but life is not that simple.
I have been in the situation where a computer bug has existed for years before it was finally tracked down and corrected.
I have also spent many days trying to find out why a critical computer program was suddenly producing lists of error reports. I eventually solved it. The big mainframe CPU had developed a fault, The last thing I expected.
Again life is not simple.
Typo correction
