The delayed adrenaline dump also occurs in emergency situations in airplanes.

As a flight instructor, I have experienced my fair share of airborne emergencies. In each case that I can easily remember, I was calm and crystal clear during the handling of the emergency and didn't get the shakes until we were back on the ground and had shut the engine down on the ramp. In one instance (engine failure shortly after takeoff), I could barely climb out of the airplane, my knees were shaking so hard.
