Bread Overhead is a science fiction short story by Fritz Leiber published in 1958.
A satire on business, advertising, and politics in the future. Bread is manufactured with the wrong gas injected at the factory, and literally becomes 'lighter than air'. While no governments topple, a secret plan for world peace advances.
'The Staff of Life suddenly and disconcertingly sprouted wings--and mankind had to eat crow!'
Bread Overhead was first published in Galaxy February 1958.
