The great slow motion YouTube channel Warped Perception has created what will probably be the best new high-speed video of the decade.  By marrying what looks to be a Vision Research Phantom Flex 4k with a Canon 600mm F4 L lens for a killer and expensive combination, they have been able to show things rarely seen in regular footage like stress on the fuselage and air dynamics impacting the aircraft as they cross paths.  Congratulations to WP for creating such an awe-inspiring video!
