looking for info on Lady Luck

Grace....According to Dick Drain's 5th Wing History of Aircraft Assigned....
Your uncle was on :

B-17  42-5133  NO NAME  342  MIA Palermo  17-4-43. Harold Schirmer crew, Murray,Price,Reed,Stout,Rossetti, Starin,Pollock,Somers,LYONS. All KIA. (MACR 3684, 16527).
 
Excerpt from Venit Hora..The Hour Has Come. The 97th Bomb Group in WW II.
 
Page 95.. Mission #92..Palermo, Sicily, Docks and shipping. 17 April 1943.
 
"A plane (342) went done in flames over the target. Two others made forced landings at Bone, N.Africa".

Note : There are "TWO"  MACRs on 42-5133. You say you have the MACR...does the MACR match one of the TWO referenced in the 5th Wing History ?
IF not, I suggest you contact LYNN_GAMMA@maxwell.af.mil and request copies of the two MACRs.
(This may take a while, as the staff has encountered a cutback in personell).

(Lady Luck in the 97th was 42-30169 which was MIA Atzersdorf 24-5-44).
There were THREE LADY LUCKs in the 5th Wing (B-17)

Grace...You might try all upper case letters or all lower case letters.  I have seen both as addresses.

Also, there is another address which also may be all upper case letters or lower case letters.

Also try a dot instead of a _ between the first and last name :

lynn.gamma@maxwell.af.mil               elsie.roberts@maxwell.af.mil

I have not, asked for any MACRs myself, so I am not sure which is correct.

Jim :-)
