Yes. People have been picked up by tornadoes. Violent tornadoes can pick up objects far larger and heavier than people.
Yes you could. You could inhale the debris that the tornado picked up. You would have to be relatively close, though.
It is very rare for a tornado to pick up a person. Tornadoes can lift debris and objects, but due to their unpredictable nature and swift movement, it is unlikely for them to directly pick up a person. It is important to seek shelter immediately in a sturdy building or underground if a tornado is approaching.
A tornado is made up of violently rotating air. It often contains moisture that has condensed as well as dust and sometimes debris that the tornado has picked up.
A rubber raft would be easily picked up, even by a weak tornado. A strong tornado could easily carry such a raft several miles. There is a good chance that the raft would be shredded by debris.
The dirt and debris picked up by a tornado are often referred to as the tornado's "debris field" or "debris cloud." This material can include soil, vegetation, pieces of buildings, and other objects that are lifted and carried by the tornado's strong winds.
the cars can get picked up by the wind
Not usually, though there have been some survivors.
After a tornado weakens and dissipates, the debris it picked up can fall back to the ground or be carried away by the wind. Items may be dropped back relatively close to where they were originally picked up or scattered over a wider area depending on the strength of the tornado.
It has happened on a few occasions. But generally your chances of survival are low if such a strong tornado picks you up.
Probably not. Most people killed by tornadoes are struck by debris, not picked up and thrown. Strapping yourself to a pole leaves you exposed and is perhaps the worst thing you could possibly do in a tornado.
It is unclear exactly which franchise this question refers to, but the first result of an internet search appears to be a store in Allen, Texas. This structure appears too large to be picked up by a tornado, but could still be completely leveled by a tornado of EF4 or EF5 strength.
Probably not at one time. While it is certainly possibly for a tornado to kill 70 or more people in a short period of time, most people who die in a tornado are not picked up, but are struck by debris or crushed in collapsing structures. In most cases of deaths, even in very violent tornadoes, bodies are found fairly close to where they originated. A large group of people standing in the open could get picked up by a large tornado, but this is a very unlikely scenario as people will usually be inside if a tornado is approaching.
