experience on a plane like this, never done it at this particular airport, does that raise any -- is 43 hours a lot? is it n a lot? >> it's not a lot, however, this pilot obviously has 10,000 hours or something close to it, has been a pilot on another large airplane, the boeing 747. but there was a supervisory pilot, an instructor, check pilot, next to him supervising him. i during my career was a check airman, one of the most enjoyable things i did was when we were hiring new pilots, to take them out after they had been through a month of ground school, to take them out on a airline flight with passengers in the back and supervise them and get them qualified to operate with a captain who wasn't an instructor. >> and to not have flown into this airport on that plane before, is that one of those data points to look at as well? how difficult is it to fly into an airport you've never flown into?
