The U.S. Army was needed to provide medical aid and resupply for a rock festival. More specifically: Woodstock. More than 400,000 people arived at the event -- more than double the number anticipated. The roads, what few there were to begin with, became bogged down with mud and stuck cars. The influx of people coupled with a lack of access, made food and medical care a concern, as Task & Purpose noted in August 2017. When one of the vendor's booths was burned down overnight -- one of the few instances of violence at Woodstock -- due to anger over inflated prices and a shortage of food, a plan was already in motion.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         As the festival kicked into high gear, Clark Stahl-a 23 year old warrant officer who'd flown medevac missions during his tour in Viet Nam, and his crew were instructed to ferry in supplies. Stall said he recalls seeing a number of other helicopters arriving at Woodstock over the course of the festival, as far as he can remember, his was the only military aircraft. "I can remember quite vividly, it's probably one of two times in my flying career, which spanned 50 years altogether, where we flew over something and were completely speechless," Stall, who left active duty in 1971 and served in the reserves until he retired in 1991, told Task & Purpose. "Seeing this mass od humanity there, it's hard to register," he continued. "There's nothing to compare it to or judge it by. Not knowing what to expect, that's probably the one thing that sticks in my mind more than anything else."                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             John Morris, the production coordinator for the festival, who was on stage when Stah's helicopter came in said, "It was like a wave." You could see people start to look up...and all I said was, "Ladies and gentlemen, the United States Army' -- and you could feel it and you could hear it, the tension -- 'Medical Corps.'  And the crowd broke into a cheer that was just fantastic. And just about then you could see the red crosses on the side." "We knew they needed to get stuff in and out of there, but the main focus was on the health and safety aspect of it, and making sure nobody had any injuries or medical issues, and if they did, they'd have the ability to treat them."  Though Stahl was back in the states and no longer cruising over the jungles of Viet Nam, in a way the mission was oddly familiar.
