For the 2008–09 "Somewhere Back in Time World Tour", he piloted Iron Maiden's chartered Boeing 757, dubbed "Ed Force One", specially converted to carry the band's equipment between continents, which subsequently led to a documentary film, "". Dickinson flew "Ed Force One" again for "The Final Frontier World Tour" in 2011. For the 2016 The Book of Souls World Tour, the band upgraded to a Boeing 747-400 jumbo jet, which meant that Dickinson had to undertake type conversion to fly the aircraft. In 2014, Dickinson purchased a Fokker Dr.I triplane replica G-CDXR and joined the Great War Display Team, which re-enacts First World War air battles at air shows across the UK.
