Yesterday a series of explosions at a fireworks market in Tultepec, a city about 40 kilometers (25 miles) north of Mexico City, killed 32 people. The city bills itself as the country’s fireworks capital. The market consisted of approximately 80 small structures from which vendors sold fireworks.
The video above of the scene after most of the explosions had run their course illustrates how a drone could enhance the situational awareness of firefighters.
CNN reports there was a similar disaster at the site 11 years ago:
After the 2005 blast, officials separated stalls at the market in an effort to prevent fires from spreading. Local government officials last week described it as “the safest market in Latin America.” In a statement, Mexican Pyrotechnics Institute Director Juan Ignacio Rodarte Cordero said the market had “perfectly designed stalls with enough space so that there is no chain reaction fire in case of a spark.”
Since the Evergreen 747 Supertanker may be coming back into our lives it might be a good time to refresh our memories of what it can do with 20,000 gallons.
These two photos was taken by a firefighter in Mexico in 2011. (UPDATE: Walt said in a comment June 20 the two photos below are from an “unpressurized ‘clean out’ (jettison)”. Videos of T979 dropping on fires show appropriate drop altitudes. One of the pilots on the clean-out jettison was a highly regarded 16-year initial attack airtanker pilot that would have mutinied if a drop on a fire was done at that AGL altitude.”)
The first video, below, is a KABC-TV News segment from May 31st, 2006 covering the 747 Supertanker demo in San Bernardino, CA. The video also includes some stock footage of the aircraft dropping during the Interagency AirTanker Board tests.
The second video below shows the 747 dropping water at Central Ciudad Real in Spain, July 21, 2009.
And next we have the 747 dropping on the Crown Fire at Anaverde, which I believe is near Palmdale, California, July 31, 2010.
And finally, below, a water dropping demo at McClellan in California, June 11, 2009.
