An RAF Tornado bomber (ZA554 - 046) flies at low level as it transits through the M6 pass in Cumbria during a training sortie.
RAF Aircraft often fly at low level to avoid radar detection. Flying at low level at high speed also reduces threats from the ground. Hills and valleys are used to hide behind as the jets make their way to targets.
This pilot skill requires much practice and regularity to maintain operational readiness.
