While I was looking for a military example of note to compliment John Becker's comment above, I found these images which I will post first since I made reference to such covers.

Additionally in the cases where the FDC airmail rate is to a foreign destination you need proof it actually went there, just an address will not do, transit or receiving marking are needed
Quote:
The same 11 cent [Prexie} used to Europe paying the 3 cent and 8 cent domestic airmail surcharge is $1150. That rate was in effect when the 11 cent was first issue and thus there are FDC of the 11 cent Prexie going to Europe and are just as rare any any other date. But for the FDC, anyone can write an address on the envelope years after it was FD cancelled and returned unaddressed. It was that example I was thinking about when I posted above that such an example required routing and or receiving marking to prove transit abroad.

Now to the 150 minute greatest last stands in naval history and the most lopsided naval victory in history. A "Commanding Officer's estimate of the situation, that is, a fight against overwhelming odds from which survival could not be expected, during which time we would do what damage we could. In the face of this knowledge, the men zealously manned their stations wherever they might be, and fought and worked with such calmness, courage, and efficiency that no higher honor could be conceived than to command such a group of men."

Military covers: Until the last decade or two, covers/letters from Korea and Viet Nam have been harder to find. They were still held by the soldiers who wrote them and their families. As they are passing away, more of this material is hitting the market.
Similarly try to assemble a set of yearbooks for a college or university. Those prior to about 1970 are easy find on the secondary (read that as "estate") market, while those from the past few decades are still held by the alumni and harder to find. It just takes time for these things to become available.
Now for the example John Becker mention about family. First is a WWII item let go by the granddaughter of the intended recipient. She did not do so lightly in 2016 and the dealer promised it a good home and exposure to an audience beyond her family. She still has postings throughout the internet asking for any information about her grandfather on his last day when as Chief Boatswain's Mate, he and his command could no longer keep the USS Hoel DD-533 afloat and operational as he was tasked to do. This Christmas parcel was send to him in September 1944 as suggested for Christmas arrival. It went to San Francisco and then some distance to the west by October 25, 1944, exactly where is unknown, then it was routed to Washington DC and again to the family in the Southern California area.


To learn why the package could not reach J. P. Goggin, CBM for Christmas, search, "The Battle Off Samar" which is considered the central action of the days long Battle of Leyte Gulf. Also read this
https://www.wtvr.com/heroes-among-u...-of-uss-hoel eyewitness description from 2021, updated 2023, from the now 98 year old last survivor of the USS Hoel, DD-533. He was only 96 when being interviewed.
Said by the commander of the Hoel, "Fully cognizant of the inevitable result of engaging such vastly superior forces, these men performed their assigned duties coolly and efficiently until their ship was shot from under them."
Below from the Korean War is an item I received from a 90+ year old legal secretary who final sold it off a few years back. She always thought it and the young sender were special. She felt it needed to find a home that would appreciate it. Surprisingly it is one of five or more C-46 items from during and just after hostilities ceased in Korea I have found. Note the wrong year in the cancel, 1942 rather than 1952. The stamp was not issued until March 26, 1952.


Edited to add missing link for interview.
