KHON2 News on Instagram: "A whole lot of people were asking “What was that?” the morning of Dec. 4 when an object was spotted falling from the sky off Oahu’s North Shore. It turns out the reported object was a flare. According to the Coast Guard, the flare was from a C-17 Aircraft belonging to the U.S. Air Force. A crew member from the aircraft confirmed they launched a single orange flare as part of search and rescue training. It was not signalling any distress. #KHON2 | #WorkingForHawaii"
