Speaking of engineers
https://ic911.org/toronto-hearings/report/toronto-report-ch-13/Physical evidence and eyewitness testimony converge to show that internal as well as external explosions went off just after 9:30 a.m., when the official narrative claims Flight 77 was still miles from Washington and did not approach the building until 9:37:46am
"The American Society of Civil Engineers states that the sole upward-thrust section of the second-floor floor slab in the alleged "plane penetration path" in Wedge One was likely due to "an independent explosion" and not impact and fire, as the official story claims that an impactor penetrated the ground floor essentially level and fire would have at the most, the report said, collapsed the second-floor floor slab downwards: "The explosion, suggested by the raised second-floor section, might represent an independent, of any lateral impact explosion." This second-floor concrete slab that was thrust upwards by a major force is, not surprisingly, above the first-floor Naval Command Center that experienced a massive and reported targeted explosion. Compare the location of the Naval Command Center with the location of the "independent explosion" that represents this upward-thrust second-floor slab, near the center of the alleged "plane penetration wedge."
