Had this audio sitting on my drive from last year waiting to be uploaded. Air Canada Rouge A319 suffered a failure of its #1 inertial reference unit (the #3 was already inop under MEL) and had to return to Orlando for an abnormal and overweight landing with the FBW reverting to direct law. The same aircraft had the same thing happen at Las Vegas six days later but I never grabbed that audio and those archives are no longer available.
