San Francisco 49ers kicker David Akers booted a 63-yarder at the end of the half against Green Bay. It's probably the most impressive kick ever made.

Here's Akers' kick, which came just before halftime against the Green Bay Packers.

Three other kickers have also hit 63-yarders: Tom Dempsey in 1970, Jason Elam in 1998, and Sebastian Janikowski last season. Both Elam and Janikowski kicked their field goals in Denver's Mile High Stadium, where the air is thinner than most NFL locations, making Akers' kick even more impressive.
