This is some fine flying. Had to share.

By the way, my house was buzzed at twice treetop level by three CAF Chinooks in formation, about a month ago. Lucky me -- I was working in the yard that day. Very, very cool. And you wouldn't believe how fast and quiet these big birds are compared to the Huey variants.
