A year after Boeing Co. slogged through a deep executive shakeup and prolonged existential crisis, the US planemaker just landed its biggest-ever aircraft order, propelled by a powerful endorsement from President Donald Trump.

The agreement comes as Qatar offered to donate a $400 million 747-8 jumbo jet for President Donald Trump to use as a temporary Air Force One.

President Donald Trump announced on Wednesday a $200 billion deal between Qatar Airways and Boeing, a lifeline for the beleaguered American aerospace giant and a powerful symbol of the diplomatic maneuvering defining his presidency.
