FFS, fuck off with your shill BS. The writers at the bottom are completely fucking wrong. The song was written by Steve Harris, Adrian Smith and Bruce Dickinson. It's off the album 'Final Frontier' which is all about leaving home and exploring new lands.
Bruce is also a fucking pilot for fucks sake, hence the lyrics. (He flies the band's 757.) It's about returning home after a long journey. Do some fucking research before posting BS like this.
