Kirbert's Airport Letterboxes
These are letterboxes that have been placed within
walking distance of General Aviation airports so that
letterboxers can hunt them by Cessna. All boxes can be
found by land as well. Some of these boxes were
planted by Kirbert, but
most were planted by others using a Kirbert stamp.
You can find these boxes by logging on to AtlasQuest.com and
conducting a search for traditional letterboxes using the
keyword "airport". This will pull up a select few that
don't contain Kirbert stamps -- people have been known to plant
their own stamps at airports -- but these may still be
useful in planning your flying trip. If you really want to
search for Kirbert stamps only, just enter "Kirbert" in the
Carver field.
Remember that, when stamping with an image of an aircraft, you
don't necessarily have to stamp with any particular
orientation. You can tilt the stamp one way so the plane
looks like it's climbing, or the other way so it looks like it's
diving. You can make it fly upside-down if you wish.
Some fixed-gear aircraft look like they're flying when stamped
level, but look like they're sitting on the tarmac when stamped
slightly nose-up. You can stamp a whole squadron of planes
flying in formation if you want to take up space in your log
book!
Just for grins, here's a link to the North Carolina Notices to
Airmen (NOTAMS) site:

This apparently has nothing to do with letterboxing, but
nonetheless involves custom-made rubber
stamp images that may be collected while visiting airports.
