there are few songs that take my intrest but Bruce Dickinson 18 minute epic about the R101 airship disaster whch put a end to the uk airship prigram of the 1930s.

https://en.wikipedia.org/wiki/R101

Beginning with a beautiful piano piece accompanied by strings and a marching snare beat, “Empire of the Clouds” remains calm while Bruce narrates the tragic R101 airship disaster of 1930. Bruce’s lifelong passion for aircraft pierces through the opus, giving “Empire” an extra sense of heart which simply cannot be manufactured. Fans may expect a turbulent 18 minutes considering the track’s subject matter, but “Empire of the Clouds” approaches chaos rather passively, instead remaining focused on theatrical mastery often found in a Broadway playhouse. Each bit of trouble never overwhelms Bruce’s narration, much like past Maiden long forms “Rime of the Ancient Mariner” or “Where the Wild Wind Blows.”
