As no one seems know the source of the image and as the captions keep changing to suit the story, it's impossible to say - arrival or departure. However, IMO what is not in doubt is that the image indicates the journey was made by SHIP...
Look closer. Who is the young woman standing close to O Senior? And why do the lei look so unnatural? Could it be the image has been tampered with? Are the 'lei' an addition to hide that he has his arm around her, and she, hers around him?
Whoever she is, she’s certainly standing very close to 0bama Sr. And she isn’t SADO.
