 According to Arnold's statement to investigators, Lahm told Dargue to "carry out his instructions" without further explanation.On January 10 the flight took place, despite a second protest from Dargue to the school commandant, Col. William A. Glassford, and became lost with its crew somewhere in Mexico.When Glassford called in Lahm, he denied authorizing the flight, and Glassford made a public announcement to that effect based on Lahm's denial.
