Once Interrupter gear was invented, the gun was used by the observer for self protection, with one or two guns fitted to a Scarff ring.  This animation also looks at the problems of aiming in aerial warfare.<br \/>\nApart from the problem of vibration from the aircraft, and the target&#8217;s manoevering, it is also necessary to aim where the target will be when the bullets reach him. The &#8216;Aim off&#8217; varies depending on the direction the target is flying.  An added problem for the observer firing a gun out the side is that the bullets also inherit the aircraft&#8217;s velocity.  For this reason, a special sight &#8216;the Norman vane&#8217; was introduced to automatically correct for the component of aircraft speed added to the bullet.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Lewis gun was one of the most widely used machine guns fitted to Allied WW1 aircraft.
