Nothing that transpired on 9/11 has ever been explained truthfully:

Wrong. None of asbestos was ever removed until it was exploded into the air. I almost went to work for the First Asbestos removal company from New Jersey, I turned it down, this is the second time they tried to bring these buildings down, before Silverstein, but whatever you think you know, is wrong.
Asbestos Use in the Construction of the World Trade Center
by Laurie Kazan-Allen
Asbestos at the WTC
Many people enquired about the presence of asbestos at the World Trade Center (WTC) last week. At that time I had no information about this subject. In awe of the superhuman efforts being made to locate survivors, I felt it inappropriate to highlight these questions. Since then, information has been forthcoming about the use of asbestos on the twin towers. One contact informed me that prior to the complex being built, the New York Port Authority had planned to use 5000 tons of asbestos-containing sprayed fireproofing on floors 1-40 of the buildings. Above the fortieth floor, non-asbestos alternatives were to be used. This is confirmed by an article which appeared in the New York Times on September 18, 2001: "Anticipating a ban (on the use of asbestos in construction in NY), the builders stopped using the materials by the time they reached the 40th floor of the north tower, the first one to go up…" According to a spokesman for the Port Authority "more than half of the original, asbestos-containing material was later replaced."
“FIREPROOFING” AT THE WTC TOWERS
Four different fireproofing materials were used during the construction of the World Trade Towers.
The initial material used for most of the fireproofing (later withdrawn because it contained asbestos) was a mineral fiber formulation consisting of about 20 percent chrysotile asbestos, 60 to 65 percent mineral wool, and the remainder made of gypsum and Portland cement binder. This was sprayed on structural steel up to the 36th floor and parts of the 37th and 38th floors of the North Tower.
Above this point in the North Tower, and for the entire structure of the South Tower, the spray was an asbestos-free successor to the original product consisting of mineral wool and binder. These formulations were applied to core columns, the outside face of the exterior walls and columns, the long-span steel joists (trusses) that supported the concrete floors, and trench headers for the underfloor raceway system.
