Robert O’Neill, a former U.S. seal who claimed to have personally killed bin Laden, posted on social media on Thursday that he had been banned from flying by Delta because he refused to wear a mask while flying on Delta. “Part of every passenger’s commitment before traveling on Delta is to comply with our latest travel policy, including wearing masks,” a delta spokesman said. If we do not comply with our regulations on wearing masks, we may not be able to fly on Delta in the future. ” O’Neill is not the first one to be banned by Dame for refusing to wear a mask. Earlier this month, delta CEO ed Bastian said the company had banned more than 100 people from flying because he refused to wear masks. O’Neill, 44, served for 15 years in the seals, the elite special forces directly under the U.S. Navy. On May 1, 2011, former US President Barack Obama announced that Al Qaeda leader Osama bin Laden had been killed by the US military. O’Neill later disclosed his identity to the US media, saying that he was the one who shot and killed. Later, a spokesman for the U.S. Department of defense confirmed that O’Neill had served in the seals. But it also stressed that it was impossible to confirm who killed bin Laden because other special forces also fired.
