Default Useless Aviation Knowledge

As the title suggests, please share the most arcane and useless bit of knowledge or factoid from your aviation career.

For example:

The stall warning disc on the B727 spins at 720 degrees per second - counterclockwise.

If you look at runway centerline lighting, it is on the opposite side of where the normal turnoff direction is(ie., right side of the centerline stripes for a left turn off). I was told this by someone once and it was true everytime I'd remember to check.

The stick shaker on the CRJ has a two minute limitation on continuous operation.

There are two tombstones located in runway 9/27 at Savannah International Airport (GA).

The number of degees of bank required to maintain an arc is equivalent to the difference between the approach course and the published lead radial.

Which two letters of the alphabet are not found on any placard on the FE panel of the 727? (I used to know, but now I can't remember.)

How many pieces of wood are there on a 727, and where are they located? (I don't remember the answer to this one either, but I knew it once.)

1. Army flight school: How many rivets in a UH-1 tailboom. I don't recall the answer.

2. How to use an ADF?

The service ceiling on Continental's old 747-200s was 45,100 feet. Don't know if that is common to all 747-200s.

Damn you! That's going to bug me enough to make me go into the basement and dig out my 727 panel foldouts. I knew that one at some point but it's been replaced by other worthless knowledge. I do remember that word "Boeing" is embossed in 7 places in the 727 cockpit...I just don't remember where (back of the yoke, on the stick shaker motor, above the trash bag holder, and ???).

OK, I have one:

Isobars as charted on an aviation weather charts rise and decent around charted high and low pressure centers at 4 millibar intervals.
