Life seems simple when you fly. Takeoff, turn to 135 degrees, and climb to 5,500 feet. After thirty minutes Copataza slides under the left wing. Turn right, follow the river, and in another five minutes, pass over Mashient. Gently lower the nose until the vertical speed indicator settles on a 500-foot-per-minute descent, and clock nine minutes more. Voilá, Charapacocha appears magically out of the jungle with the plane at pattern altitude. A clear lesson emerges. Fly straight enough to hold heading, climb high enough to miss hard things, keep track of the time, and you will reach your destination. You can’t get lost.
