Ah...yup.
They were...low.
Our family was sitting at the dinner table and ALL simultaneously said: "What was THAT!?" as our house shook with the loudest helicopter roar I've heard in this location (20+ years).
Then again, we're about 2+ miles south of the museum so they may have just descended "for effect".
