DULUTH — Navy Lt. Cary Rickoff's voice was smooth and almost gleeful at the controls of a Blue Angels F/A-18 Hornet cruising about 3,000 feet over Lake Superior.
"What I've got for you next is my personal favorite maneuver," he told me through a microphone system in my helmet as I sat fully strapped in behind him.
If I was game, he said, we would gather speed, then climb vertically into the sky, finishing it off with a corkscrew-type roll. I would need to use all my strength to fight the pull of 7 Gs — seven times the force of gravity — using a "hick maneuver" breathing technique taught to me earlier in the day: Flex every muscle in my legs and core as hard as I could, let my arms and hands lay loose, then push out a short breath making a "hick" sound and hold it for five seconds each time, all in hopes of keeping blood flowing to my brain.
I hid my apprehension. "Go for it," I said. I was on a once-in-a-lifetime Blue Angels flight, and I wasn't about to say no.
"Alriiight," he said with cool confidence. "Reaaadddyyyy. Hit it!"
Hick! Suddenly, my body felt like lead, my internal organs pushing hard into my stomach. Rickoff somehow continued to talk cheerfully, coaching me through it as I poured all my energy into trying to stay conscious.
"You're almost there," he said as I winced from the effort. "Annnd you're straight up and down. Here come the rolls."
My body jerked to the right and my mind entered a strange, dreamlike state of anxiety. I knew I had been pushing against Gs in a fighter jet, careening toward the sky and twisting, but I couldn't see anything. I couldn't push any longer to hold my breath. What was happening? Was I dreaming? Feeling lighter, I scrambled to reassure myself by grabbing for the harness and seat belts strapping me in.
