I'm still not sure what a bomb in the basement would achieve? Was it a delibrate clue left so we could all solve the puzzle?

I wonder how people still used elevators and how power was still running through the building with these columns destroyed.. You'd think there would be substantial cracking visible in things like the Naudet video from the suddenly weakened structure, and that it would have sunk, but there arn't... Why's that then?

In one way, the elevators played a heroic role that morning. They helped thousands evacuate the south tower before the second jet hit. But the elevator shafts also became the circulation system of the disaster, carrying death and destruction throughout the towers.
Elevator shafts worked like chimneys, funneling unbearable smoke to floors above the crashes. The shafts also channeled burning jet fuel throughout both towers. Fire moved not only up and down but also side to side, from shaft to shaft, unleashing explosions in elevator lobbies and in restrooms next to the shafts.
Mutuanot was in the lobby of Tower One when she heard the first explosion. Thinking it was a bomb like the terrorist attack in 1993, she turned to run, looking over her shoulder as flames leaped from a freight elevator shaft cooking her back and legs and right cheek.
"It was a fireball with sand and heat, like a hurricane of fire," she said.
The lobby windows shattered as she stumbled out of the building and fell.

My lecturer stated that previous to 911 there were known issues with the fire protection around the steel columns used for them. As a consequence when there was a fire in the twotowers the steel bars absorbed this heat and energy and hence collapse.
And just to explain to a few of you out here (sorry if you already know this) but the actual 'melting' of the bars to fail wasnt necassarily because they melted. But they actual didnt melt, but failed.

Yep, it's hearsay: Unverified information heard or received from another.

The blast wave destroys unreinforced buildings and equipment. Unprotected personnel are injured or killed as well. The antipersonnel effect of the blast wave is more severe in foxholes, on personnel with body armor, and in "stiff" enclosed spaces such as caves, buildings, and bunkers.
The overpressure within the detonation can reach 3 MPa (430 lbf/in²) and the temperature can be 2500 to 3000 °C. Outside the cloud the blast wave travels at over 3 km/s. Following the initial blast is a phase in which the pressure drops below atmospheric pressure creating an airflow back to the center of the explosion strong enough to lift and throw a human. It draws in the unexploded burning fuel to create almost complete penetration of all non-airtight objects within the blast radius, which are then incinerated

Straight from the NIST report, sry but your lecturer is not thinking for himself and and I doubt has done much independent research.

Because the account Mr Rodriguez tells, is unique to the tower he was in, and not to both towers...

And of course, ANOK, you are lecturing and teaching where?

How could he feel the building oscillate down in the basement? From his other accounts the two noises were pretty much right after each other. How does he know that the building wasn’t oscillating from the first noise?
What about his account of seeing one of the hijackers in the building before 9/11?
William had worked for the New York Port Authority for about twenty years. He was in charge of the three stairwells - A, B and C. They were narrow and without windows. There were also 150 elevators in the building. He knew the building well. His job included the maintenance of the three narrow stairwells in the class "A" building - WTC1, the north tower. On a typical morning, he would have breakfast then begin at the top of the building and methodically work his way down. Arriving at 8:30 on the morning of 9-11 he went to the maintenance office located on the first sublevel, one of six sub-basements beneath ground level. There were a total of fourteen people in the office at this time. As he was talking with others, there was a very loud massive explosion which seemed to emanate from between sub-basement B2 and B3. There were twenty-two people on B2 sub-basement who also felt and heard that first explosion.
At first he thought it was a generator that had exploded. But the cement walls in the office cracked from the explosion. "When I heard the sound of the explosion, the floor beneath my feet vibrated, the walls started cracking and everything started shaking." said Rodriguez, who was crowded together with fourteen other people in the office including Anthony Saltamachia, supervisor for the American Maintenance Company.
Just seconds later there was another explosion way above which made the building oscillate momentarily. This, he was later told, was a plane hitting the 90th floor. Upon hearing about the plane, he immediately thought of the people up in the restaurant. Then there were other explosions just above B1 and individuals started heading for the loading dock to escape the explosion's resulting rampant fire. When asked later about those first explosions he said: "I would know if an explosion was from the bottom or the top of the building." He heard explosions both before and after the plane hit the tower.
