title: Normalization/ERD for Flight Schedule
body: <p>A user who schedules planes for flights determines the type of plane to be used each day for each flight, and can change the type of plane if necessary. Normalize to 3NF and come up with a relational model. You should look at the data carefully and note details like Flight #'s are not unique, but they appear to determine other attributes.</p>

  <p>How can I normalize this? If there are no unique identifiers (primary keys) then how can this be done? I've started drawing the dependencies(below), but I'm not sure where to go from here/if I'm doing it right. </p>
