A suitable stereographic projection shows : \ mathcal L ( K ) is isomorphic to the geometry of the plane sections on a quadric cylinder over field K.
As for the M�bius plane, there exists a 3-dimensional model : the geometry of the elliptic plane sections on an orthogonal cylinder ( in \ R ^ 3 ).
With the army reform in 1975 the many light plane sections and helicopter sections were renamed squadrons and merged to form squadrons groups, equally in size to a battalion.
One notable work, often cited by others in mathematics, is " Rough draft for an essay on the results of taking plane sections of a cone " ( 1639 ).
Vorse's section was headed for Tulagi at the time and was so surprised to see the three-plane section of Val dive bombers from 5th Air Attack Force's 2nd Air Group that they almost flew past them.

But in this case the quadric lives in "'projective "'3-space : The classical real Minkowski plane is isomorphic to the geometry of plane sections of a hyperboloid of one sheet ( not degenerated quadric of index 2 ).
The top planes are attached to a centre plane-section-which, it will be observed, is peculiar in that it is arched-supported above the boat by two pairs of struts, whilst the lower plane sections are mounted on the hull.
Analogously to the classical M�bius and Laguerre planes, there exists a 3-dimensional model : The classical Minkowski plane is isomorphic to the geometry of plane sections of a hyperboloid of one sheet ( non degenerated quadric of index 2 ) in 3-dimensional projective space.
The analytic determination of the intersection curve of two surfaces is easy only in simple cases; for example : a ) the intersection of two planes, b ) plane section of a quadric ( sphere, cylinder, cone, etc . ), c ) intersection of two quadrics in special cases.
On 7 August 1942, after sighting a group of about 27 enemy bombers with escorts, Lieutenant ( j . g . ) Holt led his two-plane section through the enemy fighters, downing several, and helped to turn back the bombers, continuing his relentless attacks until his own aircraft was shot down.
