Air Force One emergency slide deployed by mistake before Trump’s Dallas trip

Military personnel accidentally deployed Air Force One’s inflatable emergency slide on the Qatar-donated jet just before President Trump was set to board for Dallas; Trump remained on Marine One for several minutes as officials inspected the slide and reassured reporters that they were simply checking the system. White House officials said there are no security concerns, though some sources noted the newer jet lacks certain security features of the older Air Force One; the flight subsequently landed in Dallas with a slight delay.
