The old guard

A pilot in a flight helmet and oxygen mask grimaces as the aircraft performs a steep maneuver, followed by another pilot with his mouth open in apparent G-force strain, then a third pilot in a yellow helmet smiling during a turn, and finally an elderly man in a blue cap and headset looking forward with a calm expression during flight. The setting is the cockpit of a high-performance aircraft, with views of the sky and ground through the canopy.
