Earth.
The stratosphere, 50 kilometers above the ground.
The stratosphere was the exact opposite of the troposphere beneath it, which lay close to the Earth's surface: cold below, hot above.
In mid-latitude regions, the stratosphere lay between 10 and 50 kilometers above the surface, while at the poles, it began at around 8 kilometers above the ground.
Above the troposphere and up to 50 kilometers above sea level, air currents mainly moved horizontally and convection weakened. This layer of the atmosphere was called the "stratosphere," also known as the "isothermal layer."
There was practically no water vapor here. The skies were clear and cloudless, weather changes were rare, and it was suitable for aircraft flight.
He-El's Manta Ray Mothership, its dark black-gold hull resembling a huge, plump, non-flat manta ray, drifted leisurely through the stratosphere, hidden within this layer.
The Manta Ray Mothership's hull was equipped with stealth reflection panels. Even if a civilian airliner passed right beside it, passengers inside would be unable to see it through their windows.
As for radar, even Wakanda, currently the most advanced nation on Earth, could not detect the Manta Ray Mothership with electromagnetic waves.
On Earth, He-El's Manta Ray Mothership was invisible.
"Hmm?"
He-El, who was making the final adjustments to synchronize the primary control pillar and secondary control pillars, suddenly raised an eyebrow.
One of the alerts he had set had been triggered.
A light screen appeared before He-El, rows of data streaming down as his gaze swept across them.
"Nick Fury's brainwave information fluctuation toward me has sharply increased by 97%!"
"Trust fluctuation amplitude: 85%!"
"Suspicion level: 100%!"
"Alertness level: 95%!"
"..."
"..."
With a single glance, He-El saw that all the brainwave fluctuation values representing Nick Fury's negative suspicions, vigilance, guesses, and the like toward him had risen to
