PREFLIGHT TRAINING NEWS AND NOTES GUARDIANS OF THE SEA. A U.S. Coast Guard helicopter returns from a rescue training mission during the USCG's Advanced Helicopter Rescue School. To fly for the Coast Guard, you must first be a USCG officer or a graduate of another armed service's flight school, and have served on active duty as a military pilot. Pilots who undergo the advanced training will work with hoist operators and rescue swimmers while coping with 36-knot winds and 20-foot waves, among other scenarios. Pilots call it the best week of flying in the Coast Guard. WHAT: Sikorsky MH-60T Jayhawk WHERE: Astoria, Oregon PHOTOGRAPHER: Chris Rose 10 / FLIGHTTRAINING.AOPA.ORGhttp://FLIGHTTRAINING.AOPA.ORG
