My internet connection was interrupted, but earlier II was going to post about the fireball because it happened at 4:50 UTC (11:50 PM CDT May 16, 2016) because it happened at the same time this magnitude 4.0 "aftershock"(?) struck La Rochelle France:

"M 4.0 - FRANCE - 2016-05-17 04:50:42 UTC"

A larger, 5.2 earthquake struck there on April 28, 2016, the largest earthquake in westernmost Europe in years:

"A magnitude 5.2 earthquake hit close to the French city of La Rochelle and port town of Rochefort on Thursday, in the strongest quake to hit mainland France since April 2014, the Central French Seismic Office said..."

The Knights Templar had a strong presence in La Rochelle since before the time of Eleanor of Aquitaine, who exempted them from duties and gave them mills in her 1139 Charter.[3] La Rochelle was for the Templars their largest base on the Atlantic Ocean,[4] and where they stationed their main fleet.[5] From La Rochelle, they were able to act as intermediaries in trade between England and the Mediterranean.[4] A popular thread of conspiracy theory originating with Holy Blood, Holy Grail has it that the Templars used a fleet of 18 ships which had brought Jacques de Molay from Cyprus to La Rochelle to escape arrest in France. The fleet allegedly left laden with knights and treasures just before the issue of the warrant for the arrest of the Order in October 1307.
