As an Oklahoman, the Synderverse Pa Kent death scene is so infuriating. Tornadoes do really weird shit - people get sucked up into powerful tornadoes and deposited miles away (& alive/with minor injuries!) all the fucking time. For example, the Lake Thunderbird tornado (EF-4) from about a decade ago hit a grocery store head on, annihilated it, but a few random aisles (including ones with glass pickle jars!) were fine & left standing. Same tornado proceeded to cross a road, hit a truck, deposited driver into a field uninjured, their truck meanwhile was destroyed/rolled into a twisted metal ball.
TLDR, if Clark saved his dad, no one would have blinked twice. & Pa Kent, being a lifelong resident of Kansas - smack dab in Tornado Alley, would have known this as well.
Heck, when I first saw Man of Steel, I actually thought Pa Kent committed suicide by tornado.
