The Warsaw radio mast, then the tallest construction ever built, collapses.
The Warsaw radio mast, the world’s tallest structure at the time, collapsed unexpectedly on August 8, 1991.
In the afternoon of August 8, 1991, the Warsaw radio mast, standing at over 646 meters, buckled and fell near Konstantynow, Poland. Engineered to transmit longwave broadcasts across Europe, it held the record as the tallest man-made structure. The collapse was attributed to maintenance errors during an antenna replacement. Though there were no fatalities, the loss disrupted communications across several countries. The incident spurred stricter safety regulations and emphasized the challenges of maintaining supertall masts.

An EF2 tornado touches down in Kings County and Richmond County, New York, the most powerful tornado in New York to date and the first in Brooklyn since 1889.
An EF2 tornado struck Brooklyn and Staten Island on August 8, 2007, the strongest recorded in New York since the 19th century.
On August 8, 2007, an EF2 tornado tore through Kings County (Brooklyn) and Richmond County (Staten Island), marking the most powerful twister ever documented in New York State. The rare urban tornado uprooted trees, damaged homes, and downed power lines across densely populated neighborhoods. It was the first confirmed tornado in Brooklyn since 1889, taking residents by surprise in a city unprepared for such storms. Despite the intensity, injuries were relatively scattered as the tornado’s path primarily affected non-peak hours. The event prompted local officials to enhance severe weather warning systems and emergency preparedness plans. Meteorologists studied the storm as evidence of shifting weather patterns in the Northeast.

A EuroCity express train en route from Kraków, Poland to Prague, Czech Republic strikes a part of a motorway bridge that had fallen onto the railroad track near Studénka railway station in the Czech Republic and derails, killing eight people and injuring 64 others.
On August 8, 2008, a EuroCity train derailed near Studénka, Czech Republic, after colliding with bridge debris, killing eight and injuring dozens.
In the early morning of August 8, 2008, a EuroCity express train bound from Kraków to Prague struck a fallen section of a motorway bridge near Studénka station. The impact caused multiple carriages to derail and flip onto their sides, resulting in eight fatalities and injuring 64 passengers. A portion of the bridge had collapsed onto the tracks just minutes before the train’s arrival, and warning systems failed to alert controllers in time. Emergency teams from both rail and road authorities collaborated to rescue survivors and clear the wreckage. The accident prompted a comprehensive review of infrastructure safety protocols where road and rail networks intersect. Improved inspection and monitoring measures were subsequently implemented to prevent similar tragedies.
