A cockpit-view GoPro video shot by Turkish test pilot shows an F-16 fighter jet gaining well over 4km in altitude in a matter of 45 seconds from the moment it starts rolling on the airfield, with the actual flight time to get there less than 20 seconds.

The F-16 B Fighting Falcon steered by Turkish TAI Test Pilot Murat Keles and rear-seat pilot Murat Ozpala simply shoots upward vertically above the clouds with such a speed that viewers physically feels the immense Gs the pilots feel while speeding up the skies and sending the jet’s engines to full throttle.
