How could an entire 47 storey steel framed building WTC 7 collapse due to a few tiny fires on a few levels?

Even the honest scientists and engineers believe there is something very strange about a building, which was not hit by any plane and did not suffer major fires, to come crashing down to the ground at free-fall speeds, over 7 hours after the collapse of the Twin Towers. The videos show that WTC 7 collapsed like it suddenly had zero strength.
When was the last time you noticed a motorcycle engine, or lawn mower engine, made of steel, start to sag or fall apart, because of fire and combustion?
That's why they are called "COMBUSTION ENGINES", because they are designed to keep working and maintain their shape even when exposed to fire.
Ordinary air fire does NOTHING to weaken steel, because steel remains very strong even up to 1100 C, when it is bright yellow or even white hot.
Air fires, no matter what type of hydrocarbon fuel you use, where the only source of oxygen is from open air at 101.3 kPa, can only get as hot as 233 to 250 C.
Don't believe me? Measure it for yourself with a pyrometer or thermal imaging camera.
That is why your car engine pistons do not distort, melt or sag when exposed to fire. The same goes for steel and aluminium frying pans & hotplates
Those Twin Towers were also designed to withstand the impact of a 707 jet plane, similar in size to a 767 jet, and they did so successfully - because they did stand strong and stable for the first 56 minutes (South Tower) or 102 minutes (North Tower, which was hit first), after jet plane impacts, showing no signs of weakness or instability.
So how gullible and stupid are you for believing the lies of 9/11 debunkers? First you believe the official lies, and then you reject the scientific evidence of controlled demolition, and choose to believe the racist, lying mass media who support this war for profit?
The same goes for building 7, which was not even hit by any plane.
Do your own thinking.
Jet fuel (kerosene) will burn at under
250 C, in an open air fire.
Because there is just not enough O2
(oxygen) to get a faster combustion
rate to raise temperatures any higher.
If you don't believe me, then try to get
molten or liquid aluminium foil to drip
off some aluminium foil, that you place
into the flames of a fire...
The melting point temperature for
Aluminium is only about 550 C.
Try to get liquid aluminium foil from any
hydrocarbon fuel (without any built in
Oxygen), using open air as the only
source of oxygen for the fire.
Tell me if you can get molten aluminium
from your own fire tests...
This experiment is very important and
will prove to you that I am 100% correct.
The try to explain all the molten metal
that was seen on ABC News and
captured on amateur video, dripping out
of the South Tower, just minutes before
YouTube search: molten metal wtc
Melting point temperature of steel is
1532 C. You can find this in any
engineering materials handbook...
So explain all the molten white hot steel
dripping out of the South Tower in those
ABC News videos, and on several
amateur videos? What is that smoking
white / yellow hot liquid dripping out of

Can fire case concrete and steel to
explode, over 10-20 floors down, where
there are no fires? That's amazing!
Look at the undenyable evidence for
planned controlled demolitions.
Ask yourself: Why was there so much
molten metal, left simmering at 600+ C
to 1000 C, for up to 8 weeks after 9/11?
These are temperatures far hotter than regular fuel-air fires!
How molten metal in the basement of Building 7, when it was not even hit by any plane?
Why don't demolition engineers use burning fuel to destroy steel buildings?
