[Elecraft] Buggy software OT

[Fred Townsend]

I think there is a big difference in flight software. In Boeing airplanes
the pilot is assisted by software. In Airbuses the pilot is allowed to fly
the airplane if the software thinks he/she is qualified. There has been at
least one airbus crash blamed on software and several other questionable
crashes. 
Unix has a dam-it key. (Dam it let me do this even though you (the computer)
think it's wrong.) I bet the airbus pilots wish they had one too.

Many moons ago I worked at a bank (software dept) and we had been running a
daily check reading program reading the magnetic line from a check and
sorting accordingly. Well this program read 600,000 checks a day - every
working day of the year (that's about 250) then after it had been running
about 6 years it fell over one day - a particular combinations of checks and
the way they were batched. Now that sounds to me like a LOT of testing
(600,000 * 250 * 6 = 900 million). So to expect all software to be perfect
is not realistic. As to not using or trusting software - well whatever you
do don't fly as all modern aircraft are software platforms!!
