NASA To Beyoncé: Challenger Disaster Should Not Be 'Trivialized'

Beyoncé fought major criticism this week after using a clip of audio recorded just after the Space Shuttle Challenger exploded in 1986, killing seven people on board.

Beyoncé, while not formally apologizing, released a statement saying the harm caused was not intentional.

"My heart goes out to the families of those lost in the Challenger disaster," the statement said. "The song 'XO' was recorded with the sincerest intention to help heal those who have lost loved ones and to remind us that unexpected things happen, so love and appreciate every minute that you have with those who mean the most to you. The songwriters included the audio in tribute to the unselfish work of the Challenger crew with hope that they will never be forgotten."

But those who lost their loved ones in the accident did not agree with using the sample in the first place. June Scobee Rogers, who lost her husband on the Challenger, said it was "emotionally difficult."
