You mean Johny Test?

Sure about that one? I would think the Concorde or America's SST would be more likely. They certainly are closer to the design used in the series.

Nope. It's the Hanna-Barbera produced Jonny Quest cartoon from 1964. It ran for 26 episodes, and was rerun on a couple of different networks for several years.

Grew up watching that baby on Saturday mornings. It had everything a young boy could want; monsters, robots, spies, explosions, super science, etc.

They rebooted it in 1986, and then again in 1996, but neither of those could overshadow the original.

What can I say, I'm a hopeless nerd.;)

I don't believe Concorde was around in '64.

And, given that the animation budget wasn't very large, they had to simplify the designs of everything. And of course, they took a few liberties with things, the cockpit of the SR-71 was not nearly as roomy as the one seen on the show.

But, one of the neat things was that, aside from the super science things of course, everything else shown was based on real things that were available at the time.

In fact, in one episode, the bad guys had state of the art assault rifles: M16's. And this was while the U.S. Army was re-equipping with those.

Boeing had a variety of SST designs using the delta-wing going back to the late 1950s. Given all the differences, I would want something definitive to link the Quest plane to the SR-71.

I hate having to admit I was wrong, but I'm going to bow to your superior knowledge of aircraft and take back my previous statement.
In fact, the only evidence I can find in support is a statement in a Comico Jonny Quest comic about it being the SR-71. And, since that was written at least 20 years after the series, I don't think it counts.:)
Should have fact checked my claims before putting them out there.
After this many years, you'd think I'd get used to being wrong by now. Guess I'm just a slow learner. ;)

Blackbird's still a beautiful airplane, though.

I would accept the Comico article, if it came from someone on the show that should know. It is just that I look at the design of the SR-71 and those of the various delta wing SST concepts, and I see a lot more similarities to the SSTs. That is why I question the plane being based upon the SR-71.

Comico licensed the characters from Hanna-Barbera, but as far as I know, no one from the show was involved with the comic.
