excerpt from Six Years Later by Impactist
The first recording of the phenomena was near the equator in Colombia. Later investigations would determine this initial occurrence was at the location furthest away from where cosmologists agree the creation of our universe began and then spread symmetrically North and South like a two dimensional plane obliquely pressing through the earth.
To the lay person, they looked like two dimensional heat mirages. About one meter wide, several miles tall, and appearing without warning. They would last only moments before they were gone. After aircraft had measured the extreme height, they were simply referred to as “Lifts” by the population. link
