...and by professionals, no less. Architects and Engineers for 9/11 truth is a good example. I'll start off with their 10 points regarding WTC 7:

As your own eyes witness — WTC Building #7 (a 47-story high-rise not hit by an airplane) exhibits all the characteristics of a classic controlled demolition with explosives: (and some non-standard characteristics)
1. Rapid onset of “collapse”
2. Sounds of explosions at ground floor - a full second prior to collapse
3. Symmetrical “collapse” – through the path of greatest resistance – at free-fall acceleration
4. Imploded, collapsing completely, and landed mostly in its own footprint
5. Massive volume of expanding pyroclastic dust clouds
6. Several tons of molten metal reported by numerous highly-qualified witnesses
7. Chemical signature of Thermite (high tech incendiary) found in solidified molten metal, and dust samples by physics professor Steven Jones, PhD.
8. FEMA finds rapid oxidation and intergranular melting on structural steel samples
9. Expert corroboration from the top European Controlled Demolition professional
10. Fore-knowledge of “collapse” by media, NYPD, FDNY

The buildings came down in a matter of seconds; the exact number of seconds is irrelevant; no steel framed building has ever come down due to fire; the windsor tower, which was only steel reinforced, not steel framed, only suffered a partial collapse, and pieces collapsed over a series of a few hours, not seconds.
