I can't describe how thick and powerful this ash is. >> well, you're right, monica. it's very dangerous. at the moment i must say it's clear skies over britain. you can't really tell that there's a problem. but there is a cloud of volcanic ash, and it's up to three miles high. and it is drifting slowly south and east from ireland. britain and holland, as you mentioned, have closed their airspaces to all but emergency flights after deeming that cloud a threat to aviation. and tens of thousands of passengers are stranded at airports across europe. you know, volcanic dust can melt inside aircraft...

Solidify again, causing mechanical problems. there have been more than 100 incidents of aircraft losing engine power in volcanic clouds since the early 1980s, although there have been no fatalities. now, aviation authorities say they have no idea when it may be safe enough to fly again. it depends, they say, on the wind and for how long that volcano keeps spewing dust into the air. savannah? >> tom aspell monitoring this situation for us in london, thanks very much. some blunt assessments by top pentagon and military officials regarding how close iran is to getting a nuclear weapon. could th...

Engine. as you may know, hybrid systems ooh electric motors for power and they switch to generators in order to slow the car down. the motor generator cannot do both at the same time, power and brake the vehicle at the same time. the system shuts off engine power to prevent damage but the hydraulic mechanical brakes are available to stop the car. the system was tested under driving conditions and found to be functioning normally. indicating that if the accelerator pedal was stuck, pressing the brake held would have resulted in dramatically reduced power to the wheels. later today we have prius...

Work and the car came safely to a stop there on the road. but since then toyota says it's performed a number of tests on that car. including tests of the system which cuts engine power should the driver depress the brakes. and depress it firmly. leaders of that japanese automaker say there are strong indications that the story being told by that driver doesn't fit. >> while our analysis is not finalized, toyota believes there are significant inconsistencies between the account of the event of march 8th and the findings of this investigation. as i mentioned this self-protection system was found...

Continuous light application in order to overheat them. the vehicle could be safely stopped by means of the brake pedal even with the overheated brakes. it's very important to note that the prius hybrid and other hybrids have a self-protective function that acts as a form of brake override. if moderate brake force is applied at the same time that the accelerator is depressed, roughly more than halfway, the hybrid system engine is cut off. fuel is cut off to the gasoline engine. now, as you may know, hybrid systems use electric motors for power and these motors switch back into being generators...
