While the first bombs were dropped from Zeppelin airships during WWI, Gotha aeroplanes showed the future. Between the wars, more bombers were built and the strategic use of aerial bombing was expanded.

When World War II breaks out, military forces immediately deploy bombers as one of the first weapons in the conflict, forcing civilians to use gas masks, construct shelters, and evacuate children from bombed-out cities.

Both sides develop tactics to maximise the combat effectiveness of the bomber and build stronger defences against the aircraft, leading to improvements in bombing, navigation, radar technology and more.

Examines the mass bombing raids after Battle of Britain across Nazi-occupied Europe and German cities, and how the US and Japan successfully bomb naval and land targets throughout the Pacific theatre.

Looks at how the bombing of Tokyo demonstrated the power of the B-29 bomber, but creating this machine cost more than developing the first atomic bomb through the Manhattan Project.

In the final year of World War II, Adolf Hitler shifts Nazi Germany's focus towards so-called `vengeance weapons', the V1 flying bomb and the unstoppable V2 rocket.
