A Zero fighter plane was brought to the observatory in the hope of finding ways to prevent atmospheric icing.

Atmospheric icing occurs when water droplets in the atmosphere freeze on objects they contact.

Aircraft use thermometers and hygrometers to determine if atmospheric icing conditions exist along their flight path.

As atmospheric icing occurs and ice builds up, a pneumatic system inflates the boot with compressed air.

All three crew members on board were killed when the aircraft struck the ground following a stall and rapid descent caused by the crew's reaction to erroneous airspeed readings caused by atmospheric icing.

The aircraft with two pilots and ten passengers on board had been on a chartered flight from La Paz to Sucre, when it encountered atmospheric icing conditions, thus being unable to maintain height.

An icing tunnel is capable of simulating atmospheric icing condition to test the effect of ice accretion on aircraft wings and body as well as to test anti-icing systems for aircraft.

The statement of the Chief of the General Staff, Gen. Doğan Güreş, that the accident on that snowy day was caused by atmospheric icing was denied by the crash investigators.

Haynes urgently requested air temperature thermometers to be supplied to all mail planes so that pilots could be warned of possible atmospheric icing conditions, but was forced to operate without them as procurement was to take two months.

November 2 - LOT Flight 703, an Antonov An-24W, crash-lands at Białobrzegi, Poland, when its engines shut down due to atmospheric icing while the aircraft is on approach to Rzeszów-Jasionka Airport.

The chief of staff, Gen. Doğan Güreş, said the accident was due to atmospheric icing but this has been denied by the manufacturer and experts from Istanbul Technical University and Middle East Technical University.

On October 15, 1943, American Airlines Flight 63, a Douglas DC-3, crashed near Centerville, Tennessee en route to Memphis after departing Nashville due to atmospheric icing on the aircraft's carburetors and wings.
