Actually, I’ve seen the post now several times he is 1/4 mile away....
If you look closely, he is just outside the fenceline to the plant! This raises a huge red flag as to way authorities had not secured the area.
The Texas City disaster was the deadliest industrial accident in U.S. history. The incident took place on April 16, 1947, and began with a mid-morning fire on board the French-registered vessel SS Grandcamp which was docked in the Port of Texas City. The fire detonated approximately 2,300 tons of ammonium nitrate[1] and the resulting chain reaction of fires and explosions killed at least 581 people, including all but one member of the Texas City fire department.[2] These events also triggered the first ever class action lawsuit against the United States government, under the then-recently enacted Federal Tort Claims Act (FTCA), on behalf of 8,485 victims.
