Oz,
The Rio incident involved an Air France 777 in feb 1999.
There is a description of the incident at
www.flightsafety.org in the flight safety digests for July 2002. You have to register to get the stuff but its free. They also mention the air NZ incident and a couple of others. I have never seen a full report on this AF event and would be interested if you find one.
Also think the Boeing aeromagazine had an article about erroneous glideslope indications recently.
Cheers,
GB
