Notes
This monster tornado formed as the Greensburg tornado was dissipating and quickly grew into a nearly 2 mile wide tornado.
Two farms received strong EF3 damage and destroyed several pieces of machinery.
A combine was thrown at least 1/4 of a mile and it disintegrated upon impact.

Notes
Officially rated high-end EF4
though the final rating was a source of controversy
and one survey team rated some of the damage as EF5.
Many homes
a large section of an apartment building
and a clubhouse were swept away
though these structures were either poorly anchored
lacked interior walls
or surrounded by contextual damage not consistent with an EF5 tornado.
A manhole cover was removed from a drain and thrown into a ravine near the clubhouse.
A 34-tonne (74,957 lb) railroad trestle support structure was thrown 100 ft (30 m) up a hill
and a 35.8-tonne (78,925 lb) coal car was thrown 391 ft (119 m) through the air.

Officially rated a high-end EF4 however
the survey conducted by NWS Norman mentions this tornado as being a "plausible EF5".
Well-built homes with anchor bolts were swept away
pavement was scoured from roads and driveways
and vehicles were thrown up to 600 yd (549 m) away
some of which were torn into multiple pieces or stripped down to their frames.
Trees were reduced to completely debarked stumps
and severe ground scouring occurred
with all grass and several inches of topsoil removed in some areas.
A reinforced concrete dome home was severely damaged and cracked.

A drillbit tornado with motion so violent the storm chaser's camera had difficulty focusing on the movement
the tornado's roar was more of a higher pitch and this stage happen a minute before it died.
Though it avoided well-built structures.
Farm equipment
two metal barns
and some outbuildings were damaged or destroyed.

At one farmstead
a house was swept away with only part of a staircase left on the foundation.
Many large trees in this area were shredded and debarked
a car was tossed and flipped onto its roof
and a gravel road was scoured and dug out to a depth of around 5 inches (13 cm).
Five wooden power poles were snapped and thrown out into a field
and two vehicle axles from an unknown location were found nearby.

Notes
Mobile Doppler radar indicated winds of 247 mph (398 km/h)
well into the EF5 range; however
only EF3 damage was observed to structures that had withstood winds from the tornado for about 45 minutes
indicating that these winds likely did not reach the surface.
Joshua Wurman
creator of the mobile Doppler radar
stated that had the tornado occurred in a populated area
there would have been EF5 damage.

Notes
Largest tornado on record at 2.6 miles (4.2 km) wide.
Was initially rated EF5 based solely on mobile Doppler radar measurements
which recorded winds over 295 mph (470 km/h).
However
the most significant structural damage was rated EF3
as the tornado did not strike any buildings when the EF5 winds were recorded.
Rating was eventually downgraded to EF3 because of this
though the practicality of the downgrade has been disputed by some meteorologists.
Famous storm chaser Tim Samaras is one of the fatalities.

Notes
Officially rated high-end EF4
though the rating was a major source of controversy
and meteorologist/civil engineer Timothy P. Marshall noted that the rating assigned was "lower-bound"
and also noted "the possibility that EF5 winds could have occurred" despite the structural flaws responsible for the EF4 rating.
Numerous homes were swept completely away with only bare slabs left
including one that was well-bolted to its foundation
and extensive wind-rowing of debris occurred.
Trees were completely debarked and denuded
shrubs were shredded and debarked
and vehicles were thrown hundreds of yards and stripped down to their frames.
A large 29,998-pound metal fertilizer tank was found approximately 3/4 of a mile away from where it originated.
Extensive ground scouring occurred as well.
