Vladimir Putin appeared rattled by Donald Trump's military jet flyover after the two leaders shook hands for the first time in six years today during a historic moment in Alaska. A B2 bomber and four F-35 figher jets flew above Putin and Trump as they walked to the US president's motorcade - a symbolic ride together into one of the most high-stakes diplomatic showdowns in decades. The Russian leader appeared shocked as the jets took off, pausing his walk to look up overhead.
