A mile wide,

A tornado can be a mile wide?? Is that the truth???

What was the biggest known tornado? The Hallam, Nebraska F4 tornado of 22 May 2004 is the newest record-holder for peak width, at nearly two and a half miles, as surveyed by Brian Smith of NWS Omaha. This is probably close to the maximum size for tornadoes; but it is possible that larger, unrecorded ones have occurred.

Yes. The Tri-State Tornado of 1925.

NOAA/NWS 1925 Tri-State Tornado Web Site--Startling Statistics
