Depending on how that three-word phrase is used, it can have two diametrically opposed meanings. As a colloquialism, “out of sight” or, more accurately, “outta sight” conjures up Boston’s seminal hit song “Rock & Roll Band” when lead singer Bradley Delp belted out Tom Scholz’s memorable lyrics:
Playin’ for a week in Rhode Island,
A man came to the stage one night.
He smoked a big cigar, drove a Cadillac car,
And said, “Boys, I think this band’s outta sight.”
But, taken in a completely different context, “out of sight” describes something that is concealed, hidden, or kept from the public eye. Consider the iconic closing scene of “Raiders of the Lost Ark,” which reveals a massive warehouse where the government seals away the Ark of Covenant inside Hangar 51 in the Nevada desert. The suggestion is that there are countless artifacts locked away in Hangar 51.
