// This file mostly supports the class "aircraft", which keeps track of
// descriptive info for one aircraft, and also the reservations for the
// use of that aircraft. The class structure is set up something like

//
// +---------------------+
// | class aircraft      |
// |---------------------|
// | descriptive         |
// | fields              |

// | reservations        |
// | (all                |
// |  reservations       |
// |  for this aircraft) |
