It is possible that #1, having taken in more gooseflesh than #2, was more compromised (due to out of balance rotating mass and damaged mounts), and simply departed first. Left loop? easy. without the nacelle for support, the wing may have dragged the water, creating more left turning impetus than the starboard side had, being "supported" by the "intact" nacelle and pylon assmbly. Who's to say?
