Zak McKracken and the Alien Mindbenders/Airplane

There are four items to collect in the airplane. On your first flight, the steward will give you peanuts, but the steward is closely guarding the other three.

Walk to the back of the airplane and enter the restroom.. Pick up the toilet paper, use the toilet paper on the sink, and turn on the sink. Push the call button, and head back into the cabin. For additional time, head to the front of the airplane, open the microwave, use the egg in the microwave, and close the microwave. Turn on the microwave to pop the egg.

With the steward distracted, you can collect three items. Pick up the seat cushion from the empty seat, and pick up the lighter that falls out. Open the overhead bins, starting at the back, and pick up the oxygen mask.

When you have all four items, you can skip the rest of the airplane sequence.
