I think it is possible to fly to orbit.Let's discuss this.This is 37,5 times lighter in wingloading than a Boeing 747.

Such a craft simply cannot attain orbital speed which is anywhere from 15,430 mph to 17,450 mph. To do this you have to get outside the Earth's atmosphere and if you do that then there's no air to give the wings on a plane any lift during the ascent phase. If you try to orbit lower where there is air then your plane will burn up due to the extreme heat which develops due to the friction between the surface of the craft and the atmosphere. If it was possible then it would have been done already. Those boys at NASA are the Jet Propulsion Laboratory are very smart.
There is a window in going to space that hasn't apparently been discovered yet.Going as slow as possible through the heating zone ( you know this..below 80 km and above Mach 10 ? ) can only be done with an aeroplane...of very lite nature.

The problem here is that you made the claim that a plane could be put into orbit. Right now it's pretty clear that you may not have a solid understanding of what it means for a spacecraft to be in orbit. And you simply cannot go to the stars with such a craft. It would take literally thousands of years to make such a flight.Being above the Earth's atmosphere is not considered to be in orbit. Being in orbit means to be placed in a circular orbit above the Earth's atmosphere. Once you've reached a height which is outside the Earth's atmosphere it can no longer fly like a plane because there is no lift. Once at that altitude you have to accelerate the craft to 17,000 mph. That's why it takes massive rocket engines to accomplish this. It requires a huge amount of work to accelerate an object to those speeds. It's not possible to do that with an airplane. Outside the Earth's atmosphere air breathing craft can't work. For one thing they need air to work, which there isn't any. Another reason is that there can be no lift because wings require air for lift. The tiny rocket engines you show on your little plane are not realistic. They have to be huge to do that kind of work. We're not talking about something like Mach 10. We're talking about just short of Mach 25!

In order to fly into space we have to learn to overcome gravity. First we must learn what gravity is and then produce machines capable of negating it. All we have to do is produce a force of a little more than 1G. Then we will slowly lift off. If we accelerate at a force of 2G's we will build up speed fairly rapidly. Perhaps in another hundred years once we understand gravity, we can travel to the moon in a few hours and mars in a few days. But that is for future technology.
