Small drones could be sidestepping Russian air defences - military expert

It's surprising to many that drones can potentially make their way from Ukrainian territory to Moscow, which sits 300 miles (483 km) behind the Russian border, says Professor Justin Bronk, a fellow at the Royal United Services Institute. Bronk says the use of small drones in warfare means these UAVs (unmanned aerial vehicles) are low-powered and have low fuel consumption engines, which means they can travel far, but slowly, with a light payload - sometimes travelling hundreds or thousands of kilometres.
