In 20 years in the industry, the reference to creating a sandbox for a program to run on is not what is expected. In this context though, is it truly accurate? I do believe that you may have missed the mark in searching for analogies when it comes to airfreight. While correct about the 461 pallets, there are several other viable options that do transport from truck, to aircraft, and to warehouse. where there could be an even greater crossover between the two systems?
