Vannevar Bush became dissatisfied with Colonel Marshall's failure to get the project moving forward expeditiously, specifically the failure to acquire the Tennessee site, the low priority allocated to the project by the Army and the location of his headquarters in New York City.
Vannevar Bush estaba insatisfeito pola lentitude coa que avanzaba o proxecto baixo o mando do coronel Marshall, e máis especificamente coa incapacidade para adquirir a localización de Tennessee, a baixa prioridade que lle asignara o exército ó proxecto e a localización do cuartel xeral en Nova York.
