In WWII the Brits had a 2 engine fighter/bomber called the mosquito. It was mostly wood, light, maneuverable and deadly because it could evade primitive German radar. This is a great idea! War will be different in the years ahead as petroleum becomes scarce. Putin has a lot of petroleum but the rest of the world, not so much. Gas is $3.80 per gal on average today. That's not cheap because of supply and demand. Unmanned vehicles like this can be small, use batteries, and save pilot lives. Lastly, check out O'Brien's "How the War Was Won" it's about WWII and how the allies crippled war production in Germany and Japan as well as mobility through things like this. That made it easier to defeat armies in the field.
