Consider the Baby, by Johann Lux

September,6 1951 a triangular shaped UFO appeared in the sky above a Wapakoneta, Ohio farm belonging to Martha and Sven Ericson.
The UFO crashed in a corn field. One hour after the crash a military convoy arrived.
Soldiers reported the craft being 15 feet long and four feet high with no visible means of propulsion and no lifeforms on-board.
Martha, holding a baby and Sven were immediately approached by men in black coats, who threatened them with death if they revealed the incident to anyone.
Decades later, UFO researchers discovered the fact, that Martha and Sven never had children.
