Will things be moving again soon?

Our television provider offers us some 300 TV channels, of which we can see about 100 without extra charges, including about 20-30 in high definition. Among these is BBC World (as well as several BBC specialty channels). It's worth having just for BBC World, which carries some excellent documentary programs as well as hourly news bulletins. This evening's BBC TV news included an item on the airline industry: several of the major international carriers have lost their patience with the meteorologists and volcanologists who are saying that the unpronounceably named volcano in Iceland could continue to disgorge vast quantities of dust and grit for weeks, even months. They've announced this evening that tomorrow they may begin air services again, volcanic dust or no. They've covered their backsides by sending planes up to test the air quality; British Airways sent up what looked like a 747; presumably they will very carefully dismantle and look inside the engines and rotor blades, as Lufthansa and Air France have done. I wonder whether Air Canada will follow the leaders (if leaders is what they are, not just reckless risk-takers). If so, perhaps we will soon see Wendy and Ivon Hurst, even though we have almost given up hope of a visit from them: if they are travelling on a fixed itinerary, they will have to by-pass Ottawa if they are delayed in London beyond tomorrow. We will soon find out.
