Aeronautical Engineers are the unsung heroes of all modern wars. If they stopped their own role, our military's air force, would just freeze, and without any airplanes, carriers are useless, and the rest of the navy(destroyers,cruisers,etc.) would have no use, and without air support, our armies will be on the retreat, and would be easy picking.That's not all, the worst part, is that our beautiful nation would be under threat from other countries, such as China,Russia, among many.
