The mysterious DC9/MD80/717 standby compass
In most commercial aircraft, the standby compass is located on the aircrafts centerline below the over head panel. In some cases, such as the A320 family, the compass can be hidden and hard to find as it can be stowed to be out of the way and out of sight since it is rarely used.

I always carried a water filled stump and a paper clip when I flew.
You really lived your life on The Edge. Hope you didn't forget to bring a leaf.
Back when I was flying the DC9, we used to use these for shaving in the cockpit.
