................I think that's right, it's been awhile since I was reading about the Komet several years ago.
.......I remember that weight was a huge dillemma for the engineers who designed the Komet because of the scarcity of aluminum & others lightweight alloys during WWII in Germany. There are no remnants of the thousands of aircraft that were shot down over German occupied Europe because every scrap was melted down and used for the German war effort. The Komet couldn't afford to carry a lead/acid battery because of its weight, I'd guess. Every small amount of weight was that much less fuel on a plane that barely had enough fuel to be launched up to bomber formations that were usually flying at high altitudes. I remember reading that the Germans recruited only their smallest pilots for the Komet and that most of them were bantam-weights compared to the average fighter pilot. There was even a plan to train women and adolescent boys to fly it that never got implemented before the war ended.
