Is Ukraine's new drone a game-changer in the war?

Kyiv, Ukraine – A mysterious weapon struck a target deep in Russia's heartland. On Monday morning, a deafening roar that sounded like a landing jet plane woke up a town spreadeagled in the flat steppes of the Volga River region. According to surveillance camera footage, a lightning-like flash followed by a thunderous explosion shook Engels, named after the philosopher and home to more than 300,000 people. It hit one of Russia's largest and most important military airfields that hosts strategic Tupolev Tu-160 and Tu-95 bombers. The planes are capable of carrying nuclear warheads, and Moscow has repeatedly used them to rain non-nuclear missiles on Ukraine.
