The track record of the B747 is far from being perfect:

61 hull losses (4% of the production), 3,846 fatalities.
The 777 has a better track record, I presume. Eight hull losses (0.47% of the production), 541 fatalities.
So I really can't see a significant safety advantage of the 747.
I kind of disagree here because when the early generation 747s entered service, aviation back then was nowhere near as robust as it is now, as literally most 1st generation jets (707, DC8, DC9, etc) were pretty unsafe.
Even still, very few of the 747 crashes were caused by design defect. The 777 was introduced at a time where aviation safety was going through a lot more reform than in the 60s and 70s.
I also don’t see how non-design related accidents in civilian sector would sway the military in favor of a twin over a 747. I don’t mean to demean your post or anything, I just disagree a bit.

Does that mean, the later / newer Boeing aircraft have not a proven track record and can't transport people safely and reliably?
We were told, that two engines are good enough for ordinary people. For the potus four engines are a requirement?

Agree with you. Raw hull losses is really misleading. For one thing, the number of cycles flown has to be considered, so hull losses per cycles flown and per km need to be brought into the calculation.

The final Boeing 747, number 1574, rolls out of the Everett factory tonight, December 6, 2022. The 747-8F is to be delivered to Atlas Air in 2023.
The first rollout was September 30, 1968, more than 54 years ago--probably before most of us were born.
Seems like a momentous occasion.

When was the last time the largest aircraft being built was a twin? Must've been the early days of aviation...

I highly doubt that anyone was worried about the perception that they are antiques or out of date. That would probably be the last impression they would ever make on a knowledgeable person.

Point of order. ALL jets are one engine away from an emergency. It's not like a quad loses an engine and the flight crew's presence is "meh..."

Didn’t BA lose one engine and continue to LHR on one flight? Does anyone remember the details?

I personally think a 777-9 should be the new AF1. Not sure why that doesn't meet the spec? 4 Engines?

Yes, there are some photos of that in the production thread. The tooling was being moved out of the main factory, and will likely be repurposed or scrapped.
Wonder if in 5 years we will have threads saying that Boeing should have maxed the 747-8 and continued production.

I get the economics of it all and completely understand the decision to call it a day, it's just hard to say good bye to a favourite. I mourned the 757 when it's line closed. Now I mourn the 747.

I’m thinking back to the BA 747 leaving the US that lost an engine shortly after takeoff. It continued without further incident to London. So I’m guessing this is a company by company decision.

Agreed, you cannot really hold bombings and runway collisions etc against the design of the plane, remove those type of events unrelated to the aircraft and what is the net number?
