Xing Feng's main frame of the "Dragon Champion" is completed, and the rest of the parts need to be tested for Mark 2's suit before the final shape can be completed.

It just so happened that the time was about the same, so Stark then skillfully changed into Mark 2's suit, activated the power system and left the underground garage.

When he came over the sea and entered the surveillance blind spot of the ground radar, Stark said impatiently: "Okay, let's see what the ability of this thing can reach. First, let's try its speed."

"Jarvis, please check it out for me, what is the record of the SR-71 Blackbird Reconnaissance Plane?"

The Blackbird aircraft was developed by Lockheed in 1959. It is a high-altitude high-speed reconnaissance aircraft and is the earliest aircraft in the world to achieve "double three".

Although it is a product of rushing ducks to be put on the shelves, there are still many unsolved problems and there is no way to carry out large-scale mass production.

But even at the global level today, it is definitely one of the greatest miracles in the history of human jet aircraft.

The significance of its existence is no less than that of Valkyrie, Concorde, A380 large passenger aircraft and Boeing 747, etc., which changes the models of human aviation history.

Currently, there are three generations of Blackbird series aircraft, and they are...

The US CIA's single-seat reconnaissance aircraft, A-12 "bullock cart" and subsequent derivatives; experimental fighter YF-12; and the US Air Force's strategic reconnaissance aircraft SR-71 reconnaissance aircraft.

These three models of Blackbird fighter jets have been manufactured one after another.

However, there are only four black birds that are already in use.

"Sir, the maximum speed of fixed-wing manned aircraft is 3.5 times the speed of sound, and the peak altitude is 95,000 feet. With the current state of the Mark 2 suit, it is still difficult to meet this standard." Jarvis analyzed rationally.

"Records are for breaking, come on!" Stark shouted excitedly, continuously increasing the main load thrust on his legs to the maximum extent.

"Bang!"

An umbrella-shaped white sound barrier appeared on Stark's head, and was then broken in the blink of an eye and moved to the middle of the legs.

“Wow——”

Feeling this powerful driving force, Stark's brain was affected by the crazy secretion of adrenaline and entered a state of extreme excitement.

"It can easily break the sound barrier with two seconds of acceleration. It's so powerful and amazing." In the underground garage workshop, Insen was stunned when he looked at Stark who turned into a streamer on the screen.

"No, supersonic speed is not the limit, its speed is still rising at an extremely fast speed."

With Xing Feng's words, the speed data monitoring on the monitor is still increasing rapidly.

468 meters per second...520 meters per second...632 meters per second...800 meters per second...

In just less than five seconds, Stark's flight speed exceeded the 800 meters per second.

That is, the speed is "2880 kilometers per hour"!

"call out--"

The Mark suit, wrapped in sonic bomb clouds, could not see its shape with the naked eye.

"Sir, the current speed has exceeded twice the speed of sound, the body temperature exceeds 400 degrees, and is climbing at a speed of 100 degrees per second. It is expected that the limit of the situation will be reached in 2 seconds. It is recommended to stop acceleration immediately." Jarvis integrated all body monitoring data and feedback to Stark.

The body self-test program will operate the entire external device of Mark's suit, and Stark wants to remove the ice condensed on the surface.
