tripoli safely. thanks, we're very glad about that. unfortunately, there are american citizens who were not able to make it out. we had a number of problems today with our flight. basically the security circumstances in tripoli radically deteriorated after friday prayers, and it was impossible i think for we think up to 90 citizens who are trying to reach our u.s. government charter at the air base to join us, so we still think that there are -- well, at least 90, possibly more, american citizens who are hoping to get out of tripoli. >> because i are heard numbers, as many as 6,000 u.s. citizens were living in libya, many of them dual nationals, but they are u.s. citizens. do they want to stay, or are they trying to get out? >> right. i really don't know the answer to that question. we don't have a complete registration system of all the americans in any country because, of course, it's a voluntary registration system so
