Three prisoners who tried to fly out of the Nuevo Laredo jail in Mexico on crude hang gliders were hospitalized Wednesday, authorities said.

The three men had prepared hang gliders from bed sheets and strips of wood at the jail in Laredo, Mexico, authorities said. When they attempted to fly off the prison wall Tuesday, they discovered the gliders were too flimsy to hold their weight.The three men dropped 90 feet, sustaining serious injuries. The prisoners were identified as Jose Gallegos, Juan de Dios Gonzalez and Jose Antonio Rodriguez. Authorities said Rodriquez was paralyzed as a result of the fall.
