Sorry for the delay replying. Incredible phenomena includes the destruction of very sturdy objects like safes, bridges, railroad tracks, and industrial equipment. It also includes the long-distance movement of very heavy objects like train cars and engines, oil tanks, cargo containers, construction equipment, and so on.

There's also strange and extreme damage which is more or less limited to F5 and EF5 tornadoes. Examples of this:

-Chip and tar pavement being rolled into piles by the 2011 Smithville, Mississippi tornado.

-Steel I-beams being twisted like noodles by the 2008 Parkersburg, Iowa tornado.

-Sheet metal roofing being wedged beneath scoured asphalt by the 1985 Niles, Ohio tornado.

-A step-up concrete porch being shattered and portions of a sidewalk pulled up by the 2011 Rainsville, Alabama tornado.

-Cars being pulled apart and scattered across fields by the 1997 Jarrell, Texas tornado.

-A rubber pump lifted out of a well by the 1974 Tanner, Alabama tornado.

-Light debris including pebbles, nails, drillbits and acorns being blown through steel roofing by the 2011 Hackleburg, Alabama tornado.
