Right it's one of "those" questions again. If an aeroplane / jet etc was to take off, then fly as fast as possible in 1 paticular direction could you in theory fly "into" space? Or would the earth rotating / gravity etc prevent this?
It's meant to say space but maybe the title was too long. So, if you were in a plan & you went vertically up say 1.5 miles, then flew horizontally you WOULD eventually end up in space?
