In February 1945, an American Liberator Bomber, "Beautiful Betsy", crashed into what is now Kroombit Tops National Park.

However, in the same month, the first froglet of this species was bred in captivity at Currumbin Wildlife Sanctuary, raising hopes that it may be saved from extinction.

[9] On 2 August 1994, the wreckage of a United States Army Air Forces Consolidated B-24D Liberator, Beautiful Betsy, was discovered in the park.

The aircraft had gone missing in stormy weather on 26 February 1945 while on a "Fat Cat" run from Darwin to Brisbane - transporting men and supplies as part of a regular flight.

[10] Eight servicemen lost their lives; six of the men were American aviators and two were British Royal Air Force Spitfire pilots.
