Pre-flight safety demonstration

[3][4] The flight attendant featured in a Delta Air Lines video from 2008 has become an internet celebrity known as Deltalina.

The former British Airways safety video, featuring several comedians, actors and other celebrities such as Rowan Atkinson, Gordon Ramsay and Gillian Anderson, is of humorous character and seeks to raise funds for the Comic Relief charity.

All airline safety videos are subtitled or shown secondarily in English as it is the lingua franca of aviation.

A safety demonstration typically covers all these aspects, not necessarily in this order: After the 1928 KLM Fokker F.III Waalhaven crash in July 1928 it was suggested that it would be good to tell passenger before a flight where the emergency exit is located.

[15] In the United States, the approval for using video for pre-flight safety demonstrations was originally included in FAA Advisory Circular 135-12, released on October 9, 1984.

Early videos from the late 1980s sometimes omit warnings about electronic devices, as it was less of a concern at the time.

Videos of this era often use 2-dimensional animation or very primitive 3D computer generated imagery to illustrate elements of the demonstration.

For instance, TWA's safety video mentioned a "slight burning odor" when oxygen masks are in use.

[citation needed] Research conducted at the University of New South Wales in Australia questions the effectiveness of these briefings in conveying key safety messages for passengers to recall and act upon in an emergency.

Two hours post exposure to the pre-flight safety briefings, recall decreased on average by 4% from the original levels across all conditions.
