Public domain film from the Library of Congress Prelinger Archive, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original).

An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, in which a person is fatally or seriously injured, the aircraft sustains damage or structural failure or the aircraft is missing or is completely inaccessible.
The first fatal aviation accident occurred in a Wright Model A aircraft at Fort Myer, Virginia, USA, on September 17, 1908, resulting in injury to the pilot, Orville Wright and death of the passenger, Signal Corps Lieutenant Thomas Selfridge.
An aviation incident is defined as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operations.
An accident in which the damage to the aircraft is such that it must be written off, or in which the plane is destroyed is called a hull loss accident...

In meteorology and aviation, TAF is a format for reporting weather forecast information, particularly as it relates to aviation. "TAF" is an acronym of terminal aerodrome forecast or, in some countries, terminal area forecast. TAFs apply to a five statute mile radius from the center of the airport runway complex. Generally, TAFs can apply to a 9- or 12-hour forecast; some TAFs cover an 18- or 24-hour period; and as of November 5, 2008, TAFs for some major airports cover 30-hour periods. The date/time group reflects the new 30 hour period in Coordinated Universal Time (UTC), as always.
TAFs complement and use similar encoding to METAR reports. They are produced by a human forecaster based on the ground. For this reason there are fewer TAF locations than there are METARs. TAFs can be more accurate than Numerical Weather Forecasts, since they take into account local, small-scale, geographic effects.
In the United States the weather forecaster responsible for a TAF is not usually stationed at the location to which the TAF applies. The forecasters usually work from a centralised location responsible for many TAFs in a state or region, many of which are over one hundred miles from the forecaster's location. In contrast, a TTF (Trend Type Forecast), which is similar to a TAF, is always produced by a person on-site where the TTF applies. In the United Kingdom most TAFs at military airfields are produced locally, however TAFs for civil airfields are produced at the Met Office headquarters in Exeter.
The United States Air Force employs active duty enlisted personnel as TAF writers. Air Force weather personnel are responsible for providing weather support for all Air Force and Army operations.
Different countries use different change criteria for their weather groups. In the United Kingdom, TAFs for military airfields use Colour States as one of the change criteria. Civil airfields in the UK use slightly different criteria...

In 1938, the Civil Aeronautics Act transferred federal responsibilities for non-military aviation from the Bureau of Air Commerce to a new, independent agency, the Civil Aeronautics Authority. The legislation also gave the authority the power to regulate airline fares and to determine the routes that air carriers would serve.
In 1940, President Franklin Roosevelt split the authority into two agencies, the Civil Aeronautics Administration (CAA) and the Civil Aeronautics Board (CAB). The CAA was responsible for air traffic control, safety programs, and airway development. The CAB was entrusted with safety rulemaking, accident investigation, and economic regulation of the airlines...
After World War II began in Europe, the CAA launched the Civilian Pilot Training Program to provide the nation with more aviators...
The approaching era of jet travel, and a series of midair collisions, prompted passage of the Federal Aviation Act of 1958. This legislation gave the CAA's functions to a new independent body, the Federal Aviation Agency...
