Before the days of GPS, finding an airport at night required keeping
the CDI centered on a VOR radial and cross referencing your position from
another VOR radial. Another thing you might be looking for is the airport
beacon which normally verifies the airport location. In the case for Skyhaven,
the beacon is not at the airport which becomes evident when lining up with
Program Replaces Physical Test Stand 12-24-16:
people do not realize that wings and tail surfaces on planes may seem fixed
and unmovable, but they are actually designed to flex under the load of
the aircraft when they lift the plane. Some articles talk about the wing
tips moving up 4 m (13 feet) before lift off. During flight as the plane
goes through turbulence, you might say that the wings are flapping up and
down around 13 feet. (YouTube has video's of this.) To ensure the wings
can take the strain, physical test stands are built to bend the wings and
horizontal stabilizers to verify mechanical operation during all the bending.
However, recently, Airbus has replaced a physical test stand with a computer
program that is saving Airbus millions in time and material costs.

Articles are showing up again about Lockheed Martin's hybrid blimp project
gone from a Skunkworks secret project for the U.S. Army to a commercial
project. It started 10 years ago with the P-791 which was modified to the
LMH-1 craft and announced to operate in Alaska through a private company
called Straightline Aviation. The blimp is helium filled and it looks like
the aerodynamic shape is a custom shaped fabric bag that is susceptible
to getting holes in it. To fix the holes, they designed a special robot
that crawls the surface of the blimp and repairs the holes when it finds
one. That sounds strange to me... CLICK

The wind snow and ice have arrived, not to mention the cold temperatures.
For many people, the cold means staying inside, but for others the winter
offers new things to do like skiing and snow machine riding. For airplanes,
cold dry air means operating at peak performance.
