you mentioned after the new york crash in october of 2006, cory lidle, the rules changed for flying around municipal areas, especially new york city. >> with the new rules in new york and no new york area, it is monitored and tight area to fly. and i would say that i would not -- fly over the hudson river, for example. a place like austin is it almost impossible to have that kind of monitoring like have you in new york after the lidle crash? >> austin is a mid-sized airport. there's not the same amount of monitoring taking place, new york, chicago or washington. and it is -- pretty tough when you see something like this happen. and be able to catch it on time. >> i want to talk to you about another type of monitoring. reagan national airport has different rules for small planes, private planes that want to fly in. we have an animation showing the flight path into reagan national. have you a knowledge of that being a flight instructor in this area. small plane pilot have to do to be able to land at reagan national airport?
