There was a company in Oklahoma that used 206’s to fly remains around back in the 70’s. I used to fly for an airline that flew to the Rio Grande Valley. Snowbirds = Bodies going home in the winter. Once had five on board.
The very worst flight(thankfully not mine) was from Frankfort Germany to Dover AFB in a MD11 flown by a good friend. Plane was empty except for one human remains being escorted home. Military remains are always escorted by someone, usually from their unit. The young man was a Navy Corpsman that was killed shortly after arriving in country. My friend went back and spoke to the escort and commented that he looked older than most escorts. He said he just kind of smiled. He asked him if he knew the man he was escorting and he said “Yes, he is my son”. The father was a former Navy Corpsman and his son served in the same unit many years apart. They opened the door leading to the cargo area and took cushions from the seats for him and let travel home closer to his son. My friend said that he HAD to let the auto land make the landing because he said that he kept tearing up.
That one was tough.
