I know what I saw with my own eyes, planes don't just disappear into thin air...
and why don't these "planes" appear on any radar?
you can think what you like, I'm just here to inform others who may be trying to seek the truth.
They do appear on radar. What they might not appear on is a hobbyist-run website. You should maybe consider reading every now and then.

Q: I was following an aircraft when it suddenly disappeared, why?
A: In most cases the reason is that the coverage from the surrounding receivers has been lost. It can also be a technical problem somewhere. Coverage at the same spot can be different depending on data source and aircraft type.
Q: Why is aircraft data incorrect or missing?
A: Flightradar24 has an extensive database detailing aircraft registration, Mode S address, age, aircraft type and more. Due to the large volume of data and continual updates there are occasionally minor inaccuracies.
Q: I own an aircraft but I cannot see it on Flightradar24. What can I do to have it displayed on Flightradar24?
A: There are a few reasons why your aircraft may not be shown. First, the aircraft may not be fitted with an ADS-B transponder meaning it is not compatible with our receiver network. Second, if the aircraft is fitted with a Mode S transponder and not visible, it may be flying in areas with little or no MLAT coverage. Third, the aircraft might be flying outside of our network in areas where we have little or no ADS-B coverage. Fourth, the aircraft might be blocked. By default we block sensitive aircraft such as those associated with military or governmental operations. For private aircraft, we can block flight tracking information at the owners request. For enquiries about aircraft blocking and unblocking, please contact us.
Q: Why don't you have coverage in my area?
A: Flightradar24 coverage is only available in areas where someone has installed an ADS-B receiver and shares data with the Flightradar24 network. We are unable to provide coverage in areas where no ADS-B receivers are installed.
Q: Why is the route information incorrect?
A: The route is not transmitted from the aircraft. We are receiving the callsign of the flight from the aircraft and comparing it with large databases of airline and airport schedules to find the matching flight number. Once the callsign is matched to a flight number, we are able to show the route of the flight. A few reasons why a route may be incorrect:
Changed flight plans
Wrong or old callsign typed into the transponder
Error in some of the schedule databases
Long flight delay, which makes the schedule data match against wrong flight
