Atomic Bomb.

This is coolbert:

From the Chicago Tribune only today:

"CHICAGO FLASHBACK"

"WWII and 'The A-Bomb'"

Seventy years ago this month the United States dropped a fearsome new weapon on the Japanese cities of Hiroshima and Nagasaki . . . Here's how the Tribune reported the momentous news"

Those Tribune headlines form the time:

"ATOMIC BOMB STORY!"

"ATOM BOMB CREW'S STORY! 60 % OF JAP CITY WIPED OUT"

"2D ATOM BOMB RIPS JAPS! REDS DECLARE WAR; ATTACK"

And as for the lead-in of the accompanying stories:

"Power of Universe Tapped to Create New Missile"

"BILLOWING FIRE BALL DIMS SUN IN DESERT TEST"

"Chicagoan Tells of Awesome Scene from Plane"

"Photographs Show Damage Outside Obliterated Zone"

Chicago, Red Gate Woods, Chicago Pile-1 and Chicago Pile-2, the Dodge Chicago factory and the engine for the B-29 bomber. That relationship between the city of Chicago and the atomic bomb project quite strong!!
