Mr. Speaker, there are many things that we could do. Certainly we could do the mechanical improvements to improve the security of the area for the pilots. There are also electronic improvements that we could do too. Each plane has an autopilot and each plane has a registered course that it is entering on travelling across the country. Certainly there are electronic means that could fix and lock the plane to that course within relative degrees of what it is going on. With those improvements to it, a plane could have a relative amount of leeway and flexibility to climb and lower.
However, as we know from the films in the United States, these planes veered a full 90° and went into other major degree turns. If they had some alley on their original flight plan of some flexibility of 20 miles, to lock it into that, it would have solved the problem right there; the planes would not have been able to veer into those buildings.
