Instead, Virgin is looking at the possibility of orbital spaceflight.
The city is physically contained by the orbital M25 motorway with its 31 junctions.
Kepler's third law of planetary motion says that the square of the planet's orbital period is proportional to the cube of its semimajor axis.
With its emphasis on accurate space flight simulation and orbital mechanics, Orbiter is not all things to all space and astronomy enthusiasts.
Suborbital and orbital transportation, however, do not require any property rights.
London's orbital M25, between junctions five and 21, was the worst followed by the A303 from Andover, Hampshire, onwards.
On February 1st they kick-started the tendering process for the extension of the M77 to Fenwick and the creation of the new Glasgow southern orbital road.
If the orbital velocity is increased, the orbit moves outward from the Sun; if the velocity is decreased, the orbit moves inward toward the Sun.
Up to 400 horseboxes could be involved, potentially bringing the orbital motorway to a standstill.
Despite Mum's apprehensions we made the motorway journey from Little Walden (north of Cambridge) down to the London orbital road and out to Portsmouth without a hiccup.
