I supposee that in this scenario, the tragedy is lessened only a little since our heroes would be coming home and have a funeral in a sense. I wonder how the American public would have reacted that day. Almost a double trauma — one when the crew perished and the second when they returned.

Fascinating research and great graphics.

Analytical Graphics (AGI) release

Revisiting Apollo 13 in STK
Wednesday, April 15, 2020, 1:00 p.m. CDT (1800 GMT)
50 years ago, the flight and ground crews of Apollo 13 overcame formidable obstacles to return three imperiled astronauts safely to Earth after an onboard explosion. 20 years ago, AGI and our partner, Space Exploration Engineering (SEE), analyzed the mission data. What we found was startling.
Using STK Astrogator – the orbit maneuvering tool we created together – AGI and SEE determined that had Apollo 13's rescue mission failed, the spacecraft would have been thrown into a fatal orbit. Five weeks after the explosion, it would have tumbled into Earth's atmosphere. That analysis differed greatly from published accounts that the spacecraft would have missed Earth by 40,000 nautical miles and orbited indefinitely.
Please join AGI and SEE for this special event, commemorating the 50th anniversary of Apollo 13. We'll discuss our recreation of the mission with STK Astrogator, the astonishing alternative conclusion we discovered, and how our team worked to resolve this mystery with two key NASA personnel from the Apollo 13 mission - lead flight director Gene Kranz and lead retrofire officer Chuck Dietrich.

I would hope that on the day Odyssey burned up in the atmosphere, there would have been a memorial service, perhaps in Arlington National Cemetery.
