Only 1800ft?? Why doest he just get on a cessna?
Heck he could just get an inexpensive round-trip fare to anywhere and could go up a few miles. Apparently this guy has never been in an airplane before or he would know the world is not flat ... and yet he wants to go up in a self-designed rocket? ha ha ha
the ceiling for a Cessna 172 is only 13,500 feet
