At that altitude, the plane would need to fly at most of orbital speed to generate enough aerodynamic and orbital lift. So with planes powered by most types of jets, they would fall out of they sky. Also, they would have have 100000 times less air to breathe, so jets would not produce a lot of thrust.

An airplane attempting to fly higher than 300,000 feet will encounter significant challenges, including extremely low atmospheric pressure and temperature, which can affect engine performance and structural integrity. Additionally, this altitude exceeds the operational limits of conventional aircraft, which are designed for commercial flight typically up to around 40,000 feet. At such extreme altitudes, specialized aerospace vehicles, like spaceplanes or spacecraft, are required to operate effectively. Furthermore, the lack of oxygen at these heights necessitates life support systems for crew and passengers.

Your question is vague. Any way if it can withstand 300000 PSI the tensile strength is higher than that. It depends on the material since Tensile strength is known as ultimate tensile strength at which level the item fails.
If an airplane attempted to fly higher than 300,000 feet, it would encounter severe challenges due to the extremely thin atmosphere, which lacks sufficient oxygen for both the crew and the engines. At such altitudes, the air pressure is so low that conventional engines would struggle to function, and the aircraft would not generate enough lift. Additionally, the intense radiation and extreme temperatures would pose significant risks to both the aircraft's structure and the occupants. In essence, no commercial or conventional aircraft is designed to operate at such extreme altitudes.
to preserve pressure at higher altidudes.
Of course airplane heights are safer than mountain heights. Mountain heights are extremely dangerous and really scary but airplane heights are more higher altitudes. Airplane heights are not that scary also it is much safer than mountain heights.
You would weigh slightly less on a mountaintop than in an airplane. This is because gravity is weaker at higher altitudes, such as on a mountaintop, compared to when you are in an airplane at cruising altitude. However, the difference in weight would be very minimal and likely not noticeable.
