History of The Weather Channel originally generated only text-based products. Radar imagery was added to the units in June of that year, with graphical backgrounds being introduced in July, making the 4000 the first STAR to be capable of generating graphics and the first to incorporate the channel's logo in the forecast segments. Also in 1990, The Weather Channel began including snow condition reports at five minutes after the hour. Largely considered the height of the classic TWC by enthusiasts, The Weather Channel underwent a major graphical revamp (with the introduction of a new slogan, "Weather You Can Always Turn To") on March 6, 1991.
Fear of flying not well understood as of 2016. It is not clear if it is really one condition; it appears to be heterogenous. It appears that people get aerophobia from being or having claustrophobia to the small spaces inside the fuselage of the plane or helicopter. The diagnosis is clinical. It is often difficult to determine if the specific phobia of fear of flight should be the primary diagnosis, or if fear of flying is a symptom of a generalized anxiety disorder or another anxiety disorder such as agoraphobia or claustrophobia. Acute anxiety caused by flying can be treated with anti-anxiety medication.
