I was working on a Cobra Attack Helicopter, back in the 80's. A Buddy of Mine was working right next to me, repairing a fastener on an engine cowling. Suddenly, He turned to Me, with a funny look on His face. I laughed as He looked really goofy. He held up His hand in front of My face, and His index finger had a #20 drill, 6 inches long run all the way through it. We were about 8 feet above the concrete floor, and I had to grab Him as He buckled at the knees. With one hand keeping Him from falling, I used the other hand to un-plug His air-drill and lowered Him to a sitting position. I got his chuck key, and released the drill from the chuck. The 6 in ch bit was halfway on each side of His index finger, but no blood, it was a tight fit, thru the bone....Our Supervisor saw this and told Me to walk Him to the Nurse's office. About half a mile in 95 degree Texas heat. I walked Him, half carrying Him all the way over there, only to get pressed into further medical service. The Nurse refused to touch it, and ordered Me to untwist the drill, by hand from His finger. I wont go into those details, but when I untwisted the drill from His finger, and the blood started to flow, She took a syringe, and filled it with RUBBING ALCOHOL.
She pushed the syringe into the bloody hole, and flushed it out with the alcohol, to remove any debris. He was as pale as a sheet.
So was I. They sent Him into town, to the Company Doctor, and I went back to My work. I need another cuppa coffee.
