When Krista and Blake were attempting an approach to pick up the sick boy, the airplane started to slow, so she told Blake to add power. The camera showed Blake's hand pulling the throttles back, toward the rear. That would reduce power and make the problem worse. To add power in an airplane, the throttles are pushed forward. Additionally, an airplane of that type, a Piper Navajo Chieftain, is normally flown by a single pilot. The pilot manipulates both the yoke and throttles at the same time.
