Fort Sam Houston in San Antonio, Texas, by train on 13 March. Two days later it arrived in Columbus with eight Curtiss JN-3 aircraft, 11 pilots and 82 enlisted men and established an airfield to the southeast of the town. From Columbus, the squadron flew its first reconnaissance sortie on 16 March. On 19 March 1916, the squadron received orders to fly into Mexico and report without delay to his headquarters at Casas Grandes. Shortly after 17:00, the planes took off but one returned almost immediately with engine problems. Darkness proved a formidable challenge and none of the aircraft completed the movement on the first day. Four landed near La Ascension, about halfway to destination, and completed the flight the next morning, although one was a total loss in a landing accident. Another aircraft overflew Casas Grandes in the dark and landed in the desert, where it was destroyed by vandals. Two others landed in the desert short of Casas Grandes, where one continued on the next morning, but the last did not arrive until repairs were completed to it on 26 March. Pershing had only five operational airplanes available for immediate duty. It was found that the squadron's Curtiss JN-3 airplanes were unable to climb over the 10,000 to mountains of the region or overcome the high winds of the passes through them. Dust storms frequently grounded the aircraft and wooden propellers de-laminated in the heat. Using its base in Columbus, the 1st Aero Squadron concentrated on carrying mail and dispatches between Columbus and Pershing's Army columns moving south into Mexico. During the last few days of March, the squadron's planes flew approximately 20 missions with messages for the various columns of Pershing's command. By 20 April, only two airplanes remained in service (neither flyable, and both were destroyed), four having crashed and two others scavenged to provide replacement parts. After the losses, the remaining two JN-3s and the rest of the squadron were ordered back to Columbus for refitting. While the Punitive Expedition searched for Villa and his men, events in the United States provided some help for the 1st Aero Squadron. Secretary of War Baker was following the squadron's activities closely. On the following day, Congress took action to deal with the deficiencies reported from Mexico. On 31 March, it passed the Urgent Deficiency Act, which provided the army with $500,000 for the immediate purchase of twenty-four
