4.1 To speed relief to isolated South Asian communities that were devastated by the December 2004 tsunami, the U.S. government doubled the number of Navy helicopters supporting the relief operation from 45 to 90 in early 2005. The Navy admiral in charge indicated that doubling the number of helicopters would provide “close to twice as much” relief. Identify the outputs and inputs and describe the production process.

Is the admiral discussing a production process with nearly constant returns to scale, or is he referring to another property of the production process?
