| My Dad was the flight line chief in Hondo Texas during WWII and had 127 planes in his care. Navigation cadets were trained in the AT-7 and AT-11 and Dad logged many hours in the co-pilot seat.
We lost Dad at age 91 August 23 2011 on the 13th day of a 14 day Alaskan cruise celebrating his 68th wedding anniversary.
Dad,s AT-7, AT-11,and engine rebuilding manuals of the 450hp engine with many others are still in his desk in perfect condition. I hope to get them from my mother this Christmas.

| Steve Johnson, I'm intrigued by your comments from July 31, 2008 about the AT-7 crash and weather and how you find "many attributes about this crash to be totally unbelievable."
Would you consider contacting me? I'd like to further explore your thoughts about the weather before I meet with people in September, 2008, from the Western Region Climate Center in Reno.

| I've been researching and studying the meteorlogical conditions of the storm and have found the incident to be full of profound weatherwise surprises. I'm very familar with this region of the Sierras having flown aboard many cloud seeding missions over Mt Darwin/Mendel and know personally how extremely dangerous crossing the Sierra Crest can be. I therefore find many attributes about this crash to be totally unbelievable. |

| In 1941, a navigator training version was put in service as the AT-7 "Navigator," which was followed in production by six AT-7As, which were modified with floats and given a large ventral fin. Of nine winterized AT-7's designated AT-7B, one was provided to Netherlands Prince Bernhard during his wartime exile, and five were supplied to the British.
The Model 18 was further modified during 1941 as the advanced trainer model AT-ll "Kansas" (subsequently renamed "Kansan"), which was intended for bombardier and gunnery training, equipped with a small bomb bay, transparent bombardier's nose section, and two .30 cal. machine guns, 1 in the nose and one in a dorsal turret.
Of the more than 1500 AT-11s built, 36 were converted to AT-11A advanced navigator trainers. A photo reconnaissance variant, designated F-2, was the final wartime run of Model 18s produced for the Army Air Force, of which 69 were acquired.

| Ok, I keep reading that there were four airmen on board. But I also keep reading that in '47 three bodies were recovered along with wreckage. Then in 2005 a fourth body was recovered. Now a fifth? Something doesn't add up. Seems like they need to exhume the three that were burred in '47 and figure out who they are as well as the new body. |

A second set of remains were found on or about August 20, 2007 at the glacier location near the 1942 crash of the
The second set of human remains was found in an alpine region oRangers located the body exposed on a remote rock glacier between granite boulders, his undeployed parachute, stenciled "US ARMY," just inches (centimeters) away. The Air Force was part of the Army until 1947.
On board were Mustonen, of Brainerd, Minnesota; pilot William Gamber, 23; and aviation cadets John Mortenson, 25, and Ernest Munn, 23, of St. Clairsville, Ohio. A blizzard is believed to have caused the crash.
The second set of human remains was found in an alpine region of Kings Canyon National Park in the Sierra Nevada range on Wednesday, as little as 50 feet from where climbers spotted the ice-entombed body of Leo Mustonen in October 2005, park officials said.

| I was part of the Helitack Crew that went to recover the the body of Aviation Cadet Leo Mustonen, age 22 of Minn. on Mt. Mendel in Kings Canyon N.P. I am so glad that his family finally has found him and has given him a proper burial. |
