Just got the latest scoop on why the CO 777 was delayed so long in Gander. Apparently there was an ETOPS regulation problem due to the fact that the plane landed in Canada. While I would like this confirmed by 777gk or calpilot, all ETOPS certifications for Continental are actually for flights to and from the US only. As the flight landed in Canada, and then was to continue to Paris, the ETOPS certification was invalidated. Continental had to get Houston to get clearance from the Canadian Aviation authority to complete the journey. Secondly the crew had written up a small repair needing done in the log-book, and as it was a new flight from Gander to Paris, the mechanics had to repair it before the flight could continue.
I had no idea that the ETOPS certification was country specific. Anyone that wishes to shout at me about this, or flame me if I am wrong on the ETOPS ruling, can take it up with the pilot from the flight as he is the source of my info
Ps, the actual reason for the diversion was a passenger medical emergency (seizure), not a crew emergency as DeltaSFO had earlier stated
