The heartbroken, longtime partner of Felix Baumgartner -- the Austrian BASE jumper and skydiver who died while paragliding in Italy this week -- has shared chilling footage of his final takeoff.
Mihaela Schwartzenberg shared the clip Friday night of Felix rising into the air ... noting in a touching tribute alongside the video that she had no idea he was beginning the final flight of his "extraordinary" life.
She went on to remember being there for nearly every one of Felix's takeoffs and landings -- from skydiving and paragliding to helicopter flights and beyond.
