What was wrong with 9/11/2001 WTC collisions ... before elections, president Trump saw them through the window, from his office ?
No ... no, no, no ... First explosion / fire took place at 8.46. First news with footage were made at 8.49 - 8.51. You had 3 minutes to get the knowledge from the crash and verify it as major news. Then you got to alter broadcasting schedule. Address and move cameras for shooting the towers. In the beginning the smoke from the burning tower was modest.

Officially second explosion took place 9.06. But CBS released the first footage from the second explosion at 8.58.
ABC, CBS, CNN, Fox and NBC had explosion in their news at 9.03.
Problem is that the towers collapsed for real, over 2000 people died and 6 000 injured.

The three minute advance would need, that checked medias knew, that there is another plane coming. From the footage you can find kind of a synchronization-confirmation code. Right before 2nd crash was brought to news, all anchors repeated the same sentences, about the crashing plane.

In the footage the 2nd plane hits the tower with low angle. The plane in the footage should have lost it's wing to the collision ( at the most ) and exploded into all around the area. Cannot swear that the moviemakers in Hollywood made the footage in forehand. But it looks like that.

Few hours after the explosion FBI found evidence from the terrorists, very conveniently. The airport personnel had failed to deliver leaders luggage to the correct, crashed plane. Most  from the people, who were in the suitcase, came from Saudi Arabia and Egypt. Not from Afghanistan and Iraq.

The event opened doors for wars in Afghanistan and Iraq. Besides almost endless news feed, over 100 000 people and another 2 000 US citizens died in these wars. Wars drained US economies, they are key reasons for current misery. Today on 20th December 2018 USA is said to struggle with debts and debt ceiling, for the second time in 2018. Struggle with ceiling means, that US government needs more debts for running the country. It is a reversed version from President Trump's pre-election promises. Talks ... nonsense ... which was targeted to common US citizens.

WTC Background data

Photo is taken 12 days after collisions. WTC has total of 7 buildings at the area.
Wingspan of the planes which collided with towers was app 53 meters. Towers were little over 63m boxes.

1st plane and collapsing tower is hinted to have destroyed WTC 7 at the top. In common terrorist strike falling and burning tower should have ruined and burned Verizon building and Old Post Office buildings too. Picture like system is possible then, when you detonate buildings with explosives. If Al Qaida hates USA as whole, quite sure, that it will not pay much attention to the buildings, their strikes destroys. 2 000 corpses, other damages and timing, rules common demolition out from the possibilities.

This picture presents you the next peculiarity. Flights 11, 93 and 77 were captured too early. US air control knows the exact locations of the planes. After hijack and radio silence, they must have noticed how Flight 11 changes it's course. Long before planes hit the towers. The preceding news footage knows nothing about almost historical hijackings in US airspace.

From this you see steels melting-softening with temperature.

Rescue Copter

With new rescue copters you can fly to the floors which are above the burning floor. Possible you need electric copter for fire fighting.
Electric copter can fly without oxygen. Smoke do not have much oxygen in it. The smoke raises from the fire, fire has used most oxygen.
Fire fighter copter needs also good radar / special vision for flights in smoke.
An electric copter with Space Lift coating and cooling tech can fly into fire. Lift can fly in the heat, where steel turns into liquid.

New rescue copter is the only vehicle, with what you can enter upper floors. Common copter could land to roof. Or hang over the roof. Rescue copter is essential in cities with over 8 floor residential / commercial buildings. Fire trucks cannot handle much higher buildings.
