Lt Homer Sprinkle and Sgt Julius Friend - DNB crash 18 Oct 1943

[Leendert]

According the 18 Oct 1943 Morning Report of the 37th FS/14th FG based in Tunisia, Lt. Homer Sprinkle and Sgt. Julius Friend got killed in an airplane crash ('Routine Training Flight'). See bottom of https://catalog.archives.gov/id/4544...objectPage=653

Accident not on AAIR or other such sites. 37th FS had P-38s at that time.
Since apparently two men in accident, is there any info (in Squadron Diary?) that points to the circumstances and/or details of airplane?

(Lt Sprinkle was in the 8 Oct 1943 shoot down of a good number of Stukas when FS was detached to Libya for a few days, but NOT subject of this thread).

Any info about 18 Oct 1843 accident welcome, thanks.
