I couldn't find the proper section to post my lastest purchase and this one seems to be the closest. I recently acquired this WWI era aviator's helmet that was worn by Lt. Charles Lester Morse whom served in the Great War.(research continues to what capacity) He later, was one of the Aviator's stationed in Hawaii and subsequently was killed in an aerial collision in 1925. The only evidence I have thus far is from published memoirs of the late Dr. R.K. Brockway.
"THE PLUCKY PIONEERS
OF ARMY AVIATION IN HAWAII:
THEY EARNED THEIR FLYING PAY!"
"For three months, there were no significant mishaps. Then on 17 July, an MB-3 pursuit plane collided with a naval plane and crashed off Fort Kamehameha killing lieutenant Landon Catlett. The stricken navy plane made a safe landing. July 27 of that year, however, was the worst day of all for air disasters. Four army aircraft crashed in three separate accidents in the course of an hour and ten minutes. There was a mid-air collision over Ford Island in which an MB-3A flown by lieutenant Charles Morse of the 19th Pursuit Squadron stationed at Wheeler Field collided with a Navy DT-2 torpedo plane piloted by Chief Petty Officer Frosio. The collision occurred just after both planes took off from adjacent airstrips, at an altitude of only 150 feet. Once again, the navy plane made a safe landing, but the MB-3A crashed and killed Morse."
If anyone has any other information, please post away!
