[Fast & Furious] Gisele and Han aren't dead

1. If Owen Shaw survived being thrown out of a car window and then a plane, Gisele could've easily tucked and rolled her way to safety. In fact, she could've shot the man behind Han knowing full well she would survive the fall. (I always laugh at this thought. The crew stands there watching the plane burn and Gisele is just a mile down the runway brushing herself off.) Especially considering she is the most tactically trained of the crew. It's easy to imagine her pulling this off.

2. For both Han and Gisele, we never see a body. There is a scene at Han's funeral but none for Gisele. Did they just not find a body or is it a simple movie editing mistake? Someone forgot to film a tombstone for Gisele"?" Highly unlikely considering the focus on Letty's tombstone in the 7th.

3. When giving over Han's personal effects to Dom, Boswell states "This was all we found. There wasn't much left really." Fire is destructive but it takes a while for it to burn through a body. Tokyo ambulances would've been on the car crash scene in no time. Remember that police were tracking the race enough for Deckard Shaw to track them. The authorities would know right where the accident was and would respond immediately (unless I'm over exaggerating Tokyo's public vehicular services). It's highly unlikely that there would be no body.

4. We don't actually see Deckard kill Han. He rams his car into Han's, walks past the car, drops the cross, and then calls Dom while the car explodes in the background. If Owen Shaw only got half his body burnt by falling out of a plane (which I still can't quite reconcile how that works), then why can't one of our main characters do the same? We've seen these people climb out of car crashes without scratches ALL THE TIME (which I realized is the biggest suspension of disbelief in these movies. Not one of these people has had whiplash or some concussive brain damage! I cry "Bullshit!").

5. We've already seen it happen. Letty. She not only survived a car crash explosion but also being blown a hundred feet through the air. Both of the ways that Han and Gisele "died". If it's plausible that she made it, even with Fast & Furious showing Phoenix "killing" her, then it's plausible for the other two to have survived similar circumstances. At least in a franchise as crazy as this.

TL;DR: Han and Gisele are alive because we've already seen other characters live through similar close-death situations.
