This happened to me when I was a kid. My family was having a picnic which included the rare treat of fried chicken. A wasp buzzed down, landed on my chicken and sawed away a chunk of it. Then it took off, faltered because the chunk was so heavy, then buzzed away. Your comparison to a helicopter is spot on! We all just sat there and watched it, not knowing what to do. We still talk about how weird that was.
