Re: UNCLE KIA WWII
In the midst of a war (especially a war on the vast scale of WWII) death often comes to large numbers of men in a short period. They must be buried quickly in less than an organized fashion. Those that die in land battles are often buried, disentered and reburied. In some cases this happens more than once.
The US had dead buried on dozens of Pacific islands and it took years after the war ended to retrieve all the remains and rebury them in a few well organized military cemetaries or send them to their families.
In the case of fliers, they could easily crash in a stretch of uninhabited jungle and not be found for years if ever.
