FOR THAT SPILT SECOND IT FELT LIKE IT WAS LOSING POWER. THEN EVERYTHING CAME BACK UP TO NORMAL. THE GAUGES WERE GREEN AND THERE WERE NO LIGHTS OR WARNINGS ON THE VEND, WE WERE STILL FLYING. SAFEST PLACE TO LAND WAS RIGHT BACK TO OUR PAD. I CIRCLED BACK AND LANDED SAFELY. ON THE GROUND EVERYTHING FELT NORMAL. NO LIGHTS OR VEND MESSAGES.
