The mission was abandoned but on taking off again from the desert 8 American servicemen died when another US helicopter collided with one of the Hercules planes.

The Shah persisted with his policy and by 1958 over 500,000 acres of land had been shared out amongst 25,000 farmers, according to a law enacted in 1955. This law fixed the maximum landholding allowed at 25 acres of irrgated land and 37 acres of non-irrigated land. The Shah also began to redistribute large landholdings owned by the Iranian Government, separate from the Crown. In 1959 the Shah attempted to enact a law forcing large private landowners to sell to the Government, which would then redistribute this land to small farmers on easy terms; the landowners blocked this measure in the Majlis.
