1. Simulate a small airport with one runway. Airplanes waiting to take off join a queue on the ground. Planes waiting to land join a queue in the air. Only one plane can use the runway at any given time. All planes in the air must land before any plane can take off.

2. Repeat Project 5, but use a priority queue for the planes waiting to land. Develop a priority schedule for situations such as low fuel or mechanical problems.

3. When each object in a collection has a priority, how should you organize several objects that have the same priority? One way is to order the objects with the same priority in chronological order. Thus, you can create a priority queue of queues. Design such an ADT.
