So Ukraine found some Russian drones.

They were surveillance drones and they appeared to have run out of gas. Ukraine fuelled them up put some duct tape over the damaged bits and sent them into Poland. Poland was ready. It had the latest and greatest American air defence system available. Poland let fly. Huge expenditure of arms and a huge drain on Poland's pocket book. So of the 19 unarmed drones Ukraine sent and after millions of dollars of American missiles fired at them 3 Russian drones were shot down the rest just ran out of gas again and landed largely intact.
