1 lonestar bottle is 9.09", 40x9.09=363.6" /12 for 30.3' (shit your guess on the football field was close on that lmao), avg male bald eagle wingspan at 76.8", 76.8x5=384" /12=32' (shit pretty close again).
Though since the article specifies a 16ft snake, the snake is only about 21.5 lonestar bottles long.
