heard. Another tornado may have also struck near Tansill in Pope County, Illinois, on the same date. Two other brief tornadoes may have hit near Westlake and at Tallulah, Louisiana, late on April 4. Dallas, Texas At around 4:30 p.m. CST (some sources say 4:15 p.m. CST), a tornado touched down in southern Dallas County, south of modern-day Interstate 20 near Redbird Airport, and traveled northward for about 45 minutes through the Dallas neighborhoods of Oak Cliff, Kessler Park, West Dallas (only west of Downtown Dallas) and Love Field before lifting over Bachman Lake, west of Dallas Love Field, just after 5:00 p.m. CST. As it first touched down, the tornado was barely visible, with only a debris cloud showing at the base of the thin funnel cloud. 13 minutes later, the tornado funnel became more visible and was seen clearly to touch the ground. The tornado reached its maximum intensity, likely in the upper range of F3, as it approached the Trinity River. In this area, between Singleton Boulevard and Riverside Drive, homes were completely swept off their foundations, and nearby railroad cars were overturned; while such damage would usually be consistent with F4 intensity, the homes had been poorly constructed, lacking wall studding and being "set on piers on center." Thus the tornado was officially rated F3, which is consistent with photogrammetric estimates of peak winds in the worst-damaged area. Some time after crossing the Trinity River, the tornado weakened, and shortly afterward passed over a parking lot about west of the U.S. Weather Bureau office at Dallas Love Field. The funnel then entered the rope stage and dissipated just north of Bachman Lake. In all, the Dallas tornado killed 10 and injured at least 200 (some sources say 216) others. Damage was estimated at $4 million (1957 USD). The tornado completely destroyed about 131 (some sources say 154) homes, badly damaged 111, and mildly damaged 287. Nearly 600 (some sources list 574) structures and more than 500 homes were damaged, including between nine and 28 permanent apartment buildings that were completely destroyed. Some businesses and schools were also damaged, but the Parkland Memorial Hospital was narrowly spared, as was Dallas Love Field. Another, though officially unconfirmed, tornado in Collin County, north of the city, may have briefly touched down just east of the dissipating Dallas tornado and caused damage. The Dallas tornado was heavily documented, filmed, and
