friends but the whole community. and there's really two stories here when you talk about the rememberances of those who lost their lives. but it's also about a city rising from the ashes. about a city that has shown such resiliency in the times since then and oklahoma city is a much stronger city than it was 15 years ago and at the same time, each year, they do this so they can remember those who were not as fortunate and lost their lives in that tragic attack, those 168 people that lost their lives on that fateful day back in april of 1995. >> all right. ron, thanks very much. we'll keep a close eye on that story. i've been at that memorial and it's quite a sight to see. the shutdowns on air travel due to volcano eruption in iceland continues to cause so much havoc for millions of travelers costing the aviation industry now at least $200 million a day. the international air transport association says it won't be feasible to "just wait until this ash cloud dissipates".
