US man who won SpaceX ticket to space gave it away after exceeding weight limit

US pilot Kyle Hippchen revealed he won a seat on SpaceX's all-civilian Inspiration4 mission last year, but had to give the ticket away because he exceeded the weight limit by 37kg. Hippchen decided to give his seat to his college roommate Chris Sembroski. Billionaire Jacob Isaacman, who sponsored the spaceflight, applauded Hippchen and called it an "incredible act of generosity".
