on a wing and a prayer

The phrase "on a wing and a prayer" is an idiomatic expression used to describe a situation where someone is barely managing or attempting to achieve something with little chance of success. It often refers to a difficult or desperate situation where the outcome is uncertain, relying solely on hope or luck rather than adequate preparation or resources. The origin of the phrase dates back to World War II, specifically referring to damaged airplanes making emergency landings with limited fuel, where the pilots had to rely on sheer determination and faith to reach their destination safely.
