This little story is mainly for the new guys just getting started,but maybe even for some of the old hands. Back in 1980 or so,i was just embarking on my ag-flying career.I was flying a Piper PA-25 PAWNEE.I had been very busy this particular morning spraying grass killer on rice.Every time i came in, one of the loader guys would load me,clean the windshield,and gas me up if i needed gas. On this load,i determined that i would get gas next time in.I landed and all of the other planes were in at the same time,so i get out and loaded my plane and clean the windshield.Totally forgot about the gas:yup: Yup,totally forgot! I start my takeoff and about the time i break ground,i remember the gas.After a quick glance at the gas guage,i decide that i had enough to make this load and get back to the flying service.About the time i get the load out,i am starting to get nervous as the guages are sitting on empty.OH CRAP,,I make a beeline for the house and about a mile and a half,Yep,she quit me.Not much time to think about it,i put it down in a bean field. Yep,the ol t-cart just ran out of gas!Called the guys over at the strip and they brought me 10 gallons,poured it in ,and went home with my pride nonexistant at this point.My point is THIS COULD HAVE BEEN MUCH WORSE!!!Please do a proper pre-flight and dont get in too much of a hurry cause what you forget to do could cost you your life. I debated with myself whether or not to tell this here,but thought it might be useful to someone. FLY SAFE T.C.
