Last week (Saturday, February 15, 2014), aircraft with registration CFBNA was "nordo" (no radio) and had an emergency landing. The aircraft circled around Ottawa Airport (CYOW) for a period of time. The pilot did an approach into Gatineau Airport (CYND), but later aborted and went back to Ottawa Airport where it did land safely. The situation, from my calculation, lasted about 31 minutes.
The Ottawa Airport tweeted this out (https://twitter.com/FlyYOW/status/434731358645391360
), but in my opinion, downplayed the statement by saying there was no emergency situation.
