Design flaw is the answer to all your question

Jim Malott explains his assessment of intrinsic design and
construction flaws of the towers which hastened their complete

Malott holds a bachelor's degree in pre-architecture from Stanford, a
master's degree in architecture from the Harvard Graduate School of
Design. Malott has studied the properties of steel-reinforced
concrete from graduate courses at the University of Delaware. He is
also a skilled welder and a practicing architect in the San Francisco
area, where he has helped design a number of high-rise buildings.
Malott has also chronicled and photographed the towers' birth from
the mid-60's to its rise and construction in the 70's.

According to Malott, before the advent of the World Trade Center
towers, high-rise buildings shared two vital characteristics: one,
they were supported by a grid of steel columns, and two, the columns
were encased in a tough cladding of reinforced concrete. This
concrete created a fireproof skin designed to withstand a four-hour
inferno. (The four-hour rating is a building industry standard for
fireproofing) As designed by architect Minoru Yamasaki the Twin
Towers incorporated neither of these traditional features. These
features were found in most tall buildings before the Twin Towers
came along and changed the equation. Malott claims that it was the
failure to use the traditional steel column grid design and concrete
coating on the steel columns that was the fatal flaw of the
buildings--not the initial crashes, not the exploding jet fuel and
not the subsequent fire alone.

Was building 7 designed like the towers or the more traditional design?
