The White House said Monday that recent "enhanced radar capabilities" may partially explain why more objects have been detected in the US airspace. John Kirby, National Security Council coordinator for strategic communications, explained during a White House press briefing that since the Chinese balloon program's "recent incursion into our airspace the United States and Canada — through (North American Aerospace Command) NORAD — have been more closely scrutinizing that airspace, including enhancing our radar capabilities." #CNN #News
