One of the most spectacular structural disasters in US hitory, but fortunately, so far very light in actual deaths
1 . WTC collapse - 2595 deaths
2. 1938 St Francis dam collapse - more than 500 deaths
3. Kansas City hyatt bridge collapse - 114 deaths
4. The Ashtabula Creek Bridge wreck 1876 - 100 deaths
5. 1998 San Francisco Loma Prieta - I-880 Viaduct collapse 40 deaths
That was an earthquake in San Fran
all of those except the WTC pale in comparison to the Johnstown Flood disaster of 1880 which killed more than 2,200 people.
Jamestown?
9/11 is the worst collapse and one of the worst disaster in American history.
BTW, the Kansas City Hyatt bridge was a suspended walkway inside the Hyatt Regency Hotel. Same reason for collapse as for this bridge in Minnesota. OVERLOADED.
