White Top

When a political conspiracy targets the White House's aircraft—only the nation's #1 air-crash investigators can save the country. The White Top helicopters of HMX-1 are known by a much more familiar name: Marine One. The S-92A, the newest helicopter in the HMX fleet, enters service after years of testing. When their perfect safety record lies shattered across a Maryland shopping mall, Miranda Chase and her team of NTSB crash investigators go in. They must discover if it was an accident, a declaration of war, or something even worse.
