Was this a US Plane? If so about what year?

My favorite as a kid. But one of the most unstable aircraft ever made.
Didn’t a 104 take out a Valkyrie?
Yeah, the F-104 was a Lockheed fighter. The reason for it's smoke trail is pretty obvious. Those two little intakes dump into one big exhaust - which means its can push more JP4 into its two engines than they can fully burn with the amount of air that can flow through those itty-bitty intakes.It’s 1/2 an F4.![]()

Kind of like the idiots you see "rollin' coal" with their diesel trucks. They're pushing more fuel into the engine than it can burn, and the excess comes out the tailpipe as black smoke (soot). Which is in fact a total WASTE!
The F4 was built by McDonald Douglas, and they fixed that smoke issue by giving each of the engines its own larger intake AND its own exhaust. This created a more free-breathing configuration that allowed it to be tuned to burn ALL of the fuel it ingested to produce usable power - rather than belching excess fuel out the tailpipe as black smoke.
Much more efficient - though maybe not quite as impressive to watch.
...and yet post-Vietnam confilct conversations with NVAF pilots revealed that the F-4 was easy to spot. It was the big black dot at the end of a pillar of smoke.In the F-4 history book I have (somewhere!) it was said that the only fix was to run one motor at flight idle and the other at minimum burner.
It has always puzzled me that the USAF and the USN put up with the J79 snorting its famous pillars of smoke as long as they did. I have read that later engines had a design change that made them smokeless, but I assume this is either untrue or the owners of this F-104 could not source an example.

B-58s had 4 J79s and in some of the low level flights, there's a smoke trail visible - not as bad as an F-4, though!
The RA-5 Vigilante was smoky, too. I read that they mitigated the smoke by using minimal afterburner.
I have a picture of a NASA Convair 880 or 990 that had smoke trails.
They do look cool!
I'd like to read that book about the F4 that you're referencing.
My dad built them during the 'Nam era, so most of what I know about them was passed on as word-of-mouth from him. Not saying he was 100% correct, just citing my source.
I don't doubt that he was at least a little biased in his opinions about this particular aircraft.![]()
