Ping!
How does one say, “Uh, we meant to do that!” in Russian?
One ping only...
I saw something similar when I was in the Navy. I was on an aircraft carrier and during our workups one of our escorts did a missile firing. The missile came out off the rails, made to big loops and into the water. I thought the ship that fired the missile was going to be hit. It was exciting but I was disappointed because I wanted to see the missile fly off and hit the drone.
