George....The normal MACR listing for an aircrew is as follows:
RW R Waist
LW L Waist
From Dick Drain's 5th Wing History of Aircraft Assigned :
42-32014 PAPPY YOKUM...347 Tranfer from 483rd BG 31 Mar 44. MIA 30 Apr 44 at Varese
Flw 14 missions. Attacked by fighters. crashed near Bologna. Harold Klein crew,Symonds, Leiby, Moore, Martin, Patzke,McGETTIGAN, Michael,Timpanereo, Kouse, Luera, (MACR 4610)
I would guess that he was flying as the ball turret gunner.
I have forwarded this to Gary Staffo, at GStaffo@gis.net
Question...are you interested in joining the 99th BG Historical Society....if so, please advise Gary Staffo.
