Post was assigned to the 25th Infantry, and reported for aeronautical duty at the Signal Corps Aviation School, Rockwell Field, San Diego, California on 26 May 1913.

[7] While descending, the Wright Model C, Signal Corps 10, suffered the collapse of a wing and the airframe dropped into San Diego Bay.

Following this accident, the Signal Corps condemned all pusher types, essentially removing Wright brothers designs from further service.

[8] The first Army aviation at Fort Sill began on 26 July 1915 when eight Curtiss JN-3 airplanes of the 1st Aero Squadron arrived from Rockwell Field, California.

The squadron was ordered to Fort Sill as a result of the Tampico Affair threatened war between the United States and Mexico.

On 26 November, the 1st Aero Squadron departed for Fort Sam Houston, from which it would eventually deploy as part of the 1916 Punitive Expedition against Mexico as a result of Pancho Villa's raid on Columbus, Texas in March 1916.

[9][10] As a result of the United States' entry into World War I, Fort Sill was selected for a primary pilot school.

Primary training took eight weeks and consisted of pilots learning basic flight skills under dual and solo instruction with a student capacity of 300.

[11] With the end of World War I, in October 1919 Post Field was deactivated as an active duty airfield in accordance with sharply reduced military budgets, and a small caretaker unit was assigned to the facility for administrative reasons to support the balloon school/company.

What was originally a five-week course was soon expanded, and special primary flight schools for prospective Field Artillery pilots were set up at Pittsburg, Kansas, and Denton, Texas.

Fort Sill has embarked on a new plan to support the museum in providing a more dynamic learning experience for the 200,000 military and civilian personnel who visit each year.

The Administrator consulted with the House and Senate Committees on Appropriations on alternatives for continuing the necessary air traffic services provided by the Fort Sill ARAC before implementing any modifications to the current operations.

[16] The Army will continue to operate and maintain a precision approach radar (PAR) at Fort Sill's Henry Post Field for the foreseeable future.

The agreement calls for the Army to continue the current level of funding for the operation and maintenance of the Fort Sill ARAC until the Sheppard RAPCON assumes the approach control responsibility.

The Army will continue to fund the precision approach radar equipment and manpower necessary to support PAR operations at Henry Post Field.
