well the glasses do look like the ones airplane pilots would wear in their time, and the jacket can be explained as one for pilots with the hair-do (mchabchal cha3ro ka2an he's been wearing something on his head) and the device thing in his hand not 100% a camera, maybe something related to the airplane
i'm insisting on him being a pilot aren't I ?
anyways even if he's a time-traveler, then I doubt he'd wear anything like this, maybe a more sophisticated outfit/looks or even maybe wear clothes like them so he would fit in, he'd be smart enough to do so I bet
