Fact check
Is it true: Delta 191 microburst windshear (Aug 2 1985)?
Yes — this is confirmed.
NTSB report (August 1986) confirmed microburst-induced windshear caused catastrophic loss of airspeed on approach to DFW Runway 17L. No TDWR existed at DFW; the crew had no actionable warning. 137 killed — 136 aboard and motorist Sherrod Williams on Highway 114. First US fatal accident definitively attributed to microburst windshear. Led to FAA TDWR deployment at 45 airports and mandatory windshear training 1988–1994.
