Given how disappointed we were with Chrissy Teigen, Nina Agdal and Lily Aldridge on the cover of the Sports Illustrated 50th Anniversary Swimsuit edition, we think the mag made a big mistake putting Kate Upton on the back of the issue!

For her third year in a row, Upton is featured on the glossy, but this time the busty 21-year-old model got bumped to the back. However, her photo shoot inside the mag is what's making the news today, as she was snapped in a zero G plane in a sexy gold bikini. SI tweeted the pic below and wrote, "Yes, we sent @KateUpton to SPACE! #SISwim50."
