Factual error: When Taya is watching TV and sees the first of the Twin Towers get hit by the suicide plane, she calls to Chris and they watch it together. Chris was born in 1974 and it states he enlisted at 30 which would've been 2004. The bar scene where Taya and Chris meet was after he completed his BUDS training and sniper school. Which, if was timeline accurate would have been 2004 or 2005. Therefore they could not have watched the events of 9/11/01 unfold together on TV because the wouldn't have known each other yet.
Suggested correction: Chris Kyle joined the Navy in 1999. Not 2004. His book American Sniper does say he was at Taya's house on 9/11. He was summoned back to the base and got caught speeding. Luckily the officer decided to not ticket him.
