Five seconds later, everyone heard a sonic boom coming from the direction of the fighter jet, chasing after it, unsure of how far it had already flown away.
Since the fighter jet wasn't flying at low altitude, although everyone heard the sonic boom, it was within an acceptable range.
"Hiss~"
Hearing this sound, Mo Jingchun gasped.
The speed just now must have exceeded Mach 5.
Truly unbelievable.
Is this thing a fighter jet? Mo Jingchun refused to believe it.
If he wouldn't believe it, let alone those Western Countries.
"Brother, what was that that just flew past?"
Candy, covering her ears, looked utterly bewildered.
"It should be a fighter jet..." Mo Jingchun himself didn't believe his own words.
"Ladies and gentlemen, just now, what flew past was our country's independently developed spaceplane prototype."
"We still have a long way to go to achieve a spaceplane in the true sense."
