World’s largest aeroplane with six Boeing 747 engines completes successful flight

The world’s largest aeroplane recently completed its second successful test flight over the Mojave Desert in California.

The Stratolaunch hypersonic test-flight carrier, nicknamed “the Roc”, took to the skies for the first time in two years.

It flew for three hours and fourteen minutes, reaching an altitude of 14,000 ft (4,267m).
 
Needs more engines

I guess it depends what is meant by "largest". The Antonov An-225 Mriya still compares well in a number of metrics.

Might have been more accurate to say longest wingspan, or something more specific.

There is a comparison table, to quote Wiki:

Strictly speaking the Stratolaunch will be an airborne carrier or mothership to be apt.
 
I thought this plane was dead, awesome!

Kinda explained in this article,


Stratolaunch resurrects its hypersonic rocket vehicle under a new name: Talon-A​


Now that it’s under new management, Stratolaunch is retooling a concept for a rocket-powered hypersonic vehicle that it first unveiled 18 months ago.

Back then, it was called the Hyper-A testbed vehicle, and it represented one of the engineering frontiers for Microsoft co-founder Paul Allen’s space venture.

A month later, Allen passed away at the age of 65 after battling a recurrence of non-Hodgkin’s disease. Stratolaunch went through a year’s worth of retrenching, leading to a change of ownership last October.

The new ownership group, led by billionaire investor Steve Feinberg, recently confirmed that it was continuing Stratolaunch’s work on hypersonic vehicles — and today it unveiled a rebranded version of the Hyper-A, now known as the Talon-A.


Stratolaunch also said it eventually intends to develop a larger hypersonic vehicle once known as Hyper-Z, and now called Talon-Z, plus a space plane nicknamed Black Ice that could carry payloads and perhaps even people to orbit.

Funny how the first plane I thought of was the Antonov when I read "largest."
 
Creative clickbait journalism at its best.
But it was at least interesting to read up on this again from a technical point of view.
 
That could be tricky to land in a crosswind. I guess it will only be operating on specialised, wider runways.
 
Having some rudimentary aeronautical knowledge from my under-grad studies, I am very curious on how this type of dual-fuselage design changes the dynamics and control of the craft.

I would imagine it is more stable, but less nimble..

According to Wikipedia it's mostly based on B747 flight systems, nothing exotic:
