Now being reported as computer failure
This is getting more into my area now:
An Air Canada flight which rolled suddenly from side to side then plunged in the air may have suffered technical problems, according to passengers interviewed after the plane was diverted to Calgary.
The pilot of Flight 190, heading from Victoria to Toronto, came over the intercom to say there had been a computer failure and that they were flying the plane manually, Richard Kool, a passenger from Victoria, said in an email to CBC News.
I am following this with renewed interest since I am presently teaching a course in computer engineering on preventing such failures!
