Can ' t understand why this isn ' t standard everywhere since it ' s a pretty handy skill to have . Most school ' s can ' t afford to buildmaintain a pool in USCanada <| sep |> Don ' t . There is way too many possibilities , many of which are country specific . You won ' t see anything from them <| sep |> I was a passenger on a turbo prop flight from Houston Bush to College Station , TX . I don ' t know that it ' s even a 45 minute flight . It was a summer day , hot and humid . There were thunder storms in the area but we weren ' t getting any rain . The flight got bumpy and then downright rough . All of a sudden we just started to fall . We were zero G ' s for at least 2 or 3 seconds . The aircraft grabbed some air and we leveled out . The pilot came over the intercom a minute later and said we were decending rapidly to avoid more of that crap . I ' ve never been so happy to be in College Station .
