The AT6 Monument is a granite memorial to Royal Air Force cadets who were killed while on a training flight during World War II.

It stands on Big Mountain, north of Moyers, Oklahoma, in the United States, and was dedicated on February 20, 2000—the 57th anniversary of the deadly crashes.

The United Kingdom was hard-pressed to train Royal Air Force cadets during World War II, since the skies over Britain were an aerial battleground.

Radiating outward from Terrell, at precise mileages, were the following stand-in cities:[1] An important part of training included frequent flight time in the cockpit.

By this point the three troubled pilots found themselves over the Kiamichi Mountains, which rise progressively in elevation from south to north.

[5] Pilot Wall and his navigator, "Wilbur" Wright, made the difficult decision to land on the floor of Impson Valley, rather than risk themselves and their plane in unknown territory.

He landed successfully in a field known as Bedford's meadow belonging to farmer and rancher Bill Perrin, outside the isolated mountain community of Jumbo.

Things took a tragic turn for the worse regarding the other two planes, which found themselves on a path several miles to the east, taking them over the rural community of Moyers, Oklahoma, behind which the mountains rise precipitously.

McMahan and other local would-be rescuers who ascended the mountain believed the fliers would have lived had the plane not impacted the tree.

Big Mountain, which marks the southern end of the rugged and geologically significant Johns Valley, is between the rural communities of Moyers and Kosoma.

Special guests included the assistant air attachés from the embassies of the United Kingdom and New Zealand, in Washington, D.C., and also the British vice consul assigned to the American Southwest, from Houston.

All three remarked that this was one of the most unusual and moving events of their diplomatic and military careers—the students, who were from a poor and rural area, had taken on an impossible task—and accomplished it themselves.

The site is easily reachable from Oklahoma State Highway 2—a sign erected by the Oklahoma Highway Patrol (originally intended for use on the day of commemoration, but also as a gift to the students by grateful troopers) guides would-be visitors from the turn-off approximately two miles north of Moyers.

Recalling that long-ago day in 1943, John Wall drew his thoughts to a conclusion, telling the students, "Turning back sooner would have been the smart thing—but then, youth always presses on.

The Choctaw Nation's Color Guard has presented and retired the colors—including Britain's Union Jack—and the Antlers chapter of Veterans of Foreign Wars has assisted, hosting receptions in its lodge hall following the ceremonies on the mountain.

During recent years a detachment of Royal Air Force officers stationed in Texas has participated, coming annually to join local residents in remembering their fallen.

School students from Rattan, some of whom are Choctaw Indians, sang “God Save the Queen” and laid roses on the “natural tombstone.”[13]
