A visit to Pensacola is not complete without a trip to this enormous collection of military aircraft muscle and artifacts. Adults and children alike will be fascinated by the range of planes on display: over 150! That's before we even get to the high-tech stuff like flight simulators and an IMAX theatre. You can watch the Blue Angels practice their death-defying air show at 8:30am most Tuesdays and Wednesdays between March and November. Best of all – it's free!
