However, his journey did not cross the equator or hit the minimum of two antipodal points as stipulated by the rules of Guinness World Records and AdventureStats by Explorersweb.

There is therefore no requirement to cross the equator, or to pass through two antipodal points, in the course of setting a round-the-world aviation record.
33.
If one wants to consider antipodal points as identified, one passes to projective space ( see also projective Hilbert space, for this idea as applied in quantum mechanics ).

Every pair of parallel lines appears to cross in two places ( antipodal points of the sphere ) . Keenan Pepper 06 : 13, 6 March 2006 ( UTC)

A point in the real projective plane can be regarded as a pair of antipodal points on the sphere . talk ) 20 : 49, 15 May 2008 ( UTC)

The antipodal quotient of the sphere is the surface called the real projective plane, which can also be thought of as the northern hemisphere with antipodal points of the equator identified.
37.
The ride must start and finish in the same place and must pass at least two antipodal points ( these are two points that line up through the earth's centre ).

Mark two antipodal points A and B on the earth at its position # 1 in the link diagram where the sun rises at A and sets at B .

Mark two antipodal point C and D on the earth at its position # 2 in the link diagram where the sun rises at C and sets at D .

A diagram illustrating great-circle distance ( drawn in red ) between two points on a sphere, P and Q . Two antipodal points, u and v, are also depicted.
