Well, OK, maybe once

    When people find out I'm a flight instructor, the first thing out of many of their mouths is, “don't you get scared flying with those new wannabe pilots?” My canned answer is no, flying with new students is no more stressful than driving down a busy street or standing in a long line at WalMart (actually, the WalMart thing is much more stressful and more likely to produce a life-changing event). I seldom go to the next level of answer, the level that goes back 25 years or so, back to that flight with that students whose name I have long-since forgotten. The guy who almost got us both killed.
     As I recall, the flight in question was this guy's third or fourth lesson. He had been a good student, always showed up on time, had his homework done, listened carefully to instructions – the works. We had already been through some of the basics of flight, like climbs and descents, turns, and even some ground reference maneuvers where we circle around a point on the surface and try to keep the airplane at the same altitude and distance from the reference. He had done fine, no remarkable problems or learning issues. So we went to the next step.
    That next step was what we call 'stall recognition and recovery.' Airplanes stall when their wings no longer produce enough lift to keep the thing going. Normally it happens because the pilot slows the airplane down too much or pitches the nose of the plane up too high. Left unchecked, a stall can turn into a spin, and a spin into a crash, with widely scattered aluminum and sadness for those left behind. Not good.
    To dramatically reduce the chance of this scenario actually playing out in the real world, we teach students how to recognize an impending stall and how to prevent it from occurring, We also teach them how to recover from a stall early in the process so it doesn't degrade into a spin. It's really not complicated. All the pilot has to do is lower the nose of the airplane to just below the horizon (what we call 'decreasing the angle of attack'), add power and let the airplane go back to being its normal, docile self.
    Many students are terrified of stall training, especially in the early phases of instruction. The thought of flying a mile above the earth and putting the airplane into a configuration where the wings stop flying produces more than a little nervous laughter during the pre-flight ground briefing. “We're going to do WHAT??” is often written all over their faces. I don't recall this student being any more apprehensive than normal during the pre-flight, so we climbed into the plane, got our clearance, and took off for the practice area.
    At that time, I was flying out of Buchanan Field in Concord, California, a medium sized city just east of San Francisco. The practice area was just north of the field, midway between Concord and Travis Air Force Base. The area was flat and deserted, populated only by migrating birds and the occasional Tule Elk. Small canals and sloughs wind their way through the area, forming marshy swamps in many areas. More than one airplane has been pulled from those bogs over the years due to gas starvation or mechanical malfunction. I always thought there must be snakes down there, lots of them. I hate snakes.
    The lesson started smoothly enough. Normally, the instructor demonstrates a new maneuver to the student, explaining it as he/she goes along. Then, the student does it, with the instructor keeping a close eye (and closer hands) on the control inputs. I showed the student how to do clearing turns to make sure there was no conflicting traffic in the area. We then applied carburetor heat, reduced the power, slowed the airplane to the appropriate speed, lowered the flaps and established a power-off glide. Then, we gently lifted the nose of the airplane to just a few degrees above the horizon and watched the airspeed bleed off as the plane tried to climb uphill with the engine idling. Keeping back pressure on the yoke, we waited for the stall warning horn to go off, telling us that we're just a few MPH above stall speed. At that point, we lowered the nose to just a degree or two below the horizon, added full power, and lifted the flaps to 20 degrees. We then lifted the nose just a little above the horizon to establish a positive climb rate, waited a few second, then lifted the flaps the rest of the way up, establishing normal cruise airspeed. No sweat, and almost no loss of altitude throughout the entire maneuver. I did the whole thing one more time with the student just watching, to give him a chance to chill a little and take in the steps one more time. Then it was his turn.
    The first few steps went fine. We did our clearing turns and reduced the power to idle. As I reminded him to start lowering flaps, I could see him leaning forward in his seat as though bracing for an impact of some sort. OK, no worries, most students are little nervous during these first few stall exercises. When he lifted the nose to slow down to begin the stall sequence, he pulled back way too far on the yoke and the airplane pitched up far above the horizon, slowing much too quickly. This rapid slowing caused the stall warning horn to blast its message almost immediately, and when it did, rather than pitching the nose down to just below the horizon, he pushed the yoke all the way forward to its stops, causing the plane to pitch down violently. All the papers and contents laying in the back seat lurched immediately to the ceiling. Pens flew out of my pocket, and my head hit the headliner. Hard. We must have pulled negative 2 Gs, and we were going as close to straight down as I have ever been while not doing aerobatics. To make matters worse, the student had applied full power (as he should have), increasing our speed dramatically and bringing the earth closer to us at an alarming rate. “I have the airplane,” I called out, probably an octave or two higher than normal. When an instructor says this to a student, it means for the student to let go of the controls and the instructor will fly it back to a more normal configuration. Only this time, the student was frozen on the controls and did not let go. That's when I got a little, eh, anxious. “I have the plane,” I repeated. Again, no response. We were now probably 2500 feet above the ground and closing fast. The student had both hands on the control yoke and would not let go. At least I could reduce the power, so I did, which slowed our descent rate a little, but we were still headed straight for those swamps and those damn snakes. I called out for him to let go of the controls two or three more times, but he was frozen in terror. Finally, at an uncomfortably low altitude and with a windshield still full of marsh land, I jabbed the student as hard as I could in the ribs with my elbow. That did the trick. He let go, either from pain or shock, and I took the controls and got is straightened out. We flew in silence back to Buchanan. I never saw the guy again. I tried calling him a few times to talk about what happened, but I never heard back. Too bad.
    Though a scary story, I can honestly say that was the only time in decades of boring holes in the sky with new students that I was actually afraid. Most flights and lessons are learning experiences that slowly, over time, turn a a dreaming wannabe into a safe, confident and competent pilot, with a life changed forever through the experience of controlled flight through the earth's atmosphere. Mankind has dreamed of doing just that for millennia, and it is every pilot's duty and pleasure to share that experience with as many people as possible.
    When I recounted that story to people right after it happened, one or two asked if I was going to quit teaching as a result of the experience. Frankly, the thought never occurred to me. They say that piloting a plane is hours of boredom punctuated by seconds of sheer terror. I don't believe it. Flying for me has been years of sheer joy and sharing, punctuated by one guy who freaked out and scared us both for a few moments of uncertainty. It was nerve wracking for awhile, but not terrifying, certainly not enough so to keep me from helping others realize their dreams of flight.
    No way was I going to let a little muddy water and a few measly snakes keep me from showing newbies the view from Up There. No way.
