(Newser) – The monster tornado that tore through an Oklahoma City suburb is one of the worst on record by most standards, the Smithsonian finds. At an estimated two miles wide, the storm was one of the biggest recorded and it was also extremely powerful, with winds above 199mph. But what made it especially deadly was its duration—it was on the ground for 40 minutes, while most tornadoes only last for a few minutes.

  • The strongest tornado ever recorded, with winds of 302mph, struck May 3, 1999, in Moore, Okla., the same place that was devastated by yesterday's tornado, the Atlantic notes.
  • The 1999 Oklahoma tornado was the deadliest since a tornado in Wichita Falls, Texas, killed 42 people on April 10, 1979, but it has been surpassed by several since, including the May 22, 2011, tornado that killed 158 people in Joplin, Mo.
  • The worst tornado on record in the US was the "Tri-State" tornado that killed 695 people in Missouri, Illinois, and Indiana on March 18, 1925. That storm stayed on the ground for three and a half hours and killed 234 people in Murphysboro, Ill., alone.

Let's see if the Democrats tie up disaster relief like the Republicans did for Sandy.

Both Sens. Coburn & Inhofe of Oklahoma voted NO on the Sandy Relief Bill. Both picked apart the Sandy Relief Bill looking for "pork" which delayed aid for over 3 months Both wanted to cut funding from other agencies to help pay for Sandy Relief which delayed aid for over 3 months Will they be as fiscally responsible this time around? Let the hypocracy begin Prays go out to the people of Oklahoma.....I hope federal aid does not take as long as it did for the victims of hurricane Sandy

Beyond it all, people still make this about politics....sad. Families have been killed and so many want to talk about Lefty and Righty. Seems to me that's where many are missing the mark. We shelled out a few hard earned dollars this morning to help out the best we can. (and yes, I know it will make it there because it's a fund we're involved with consistently) If everyone did that we wouldn't have to depend on the government and all that drama that goes with it.
