operations procedures. we're going to review the bench testing of the angle of attack indicator. and then we're going to return it back to service and we're going to look at updating the manuals. they haven't -- that's a lot of looking at and reviewing and checking. you know, that's important stuff. and that puts me a little bit more at ease knowing that that went out to the international community and that every one of these airplanes is required to have that done. but it's not enough. it's still not enough, don. there's many things that they still need to do to make sure that this aircraft is safe. >> i want to put up the top three airlines using the plane in north america. and again, this is according to the "times." is it safe to fly these planes? >> don, you know, let me put it this way. i would go. i would fly these airplanes myself. would i opt to take a vacation right now and bring my granddaughter with me? probably not.
