I make no claims of being an expert, and of course I wasn't there to know all the ins and outs, however reading that F100 report there is not one questioning mention about the crew having received a cockpit warning of windshear only added 5 knots to their speed???
Because the windshear warning was probably only momentary. If you had experience in these types in the conditions they were in, you would realise WS warnings occur on a regular basis and are generally "spurious". The F100 doesn't have a high-speed wing and so +5 could be quite acceptable.
I would be more questioning about the airport operator that doesn't have a VHF AWIS or a windsock at the threshold (not shown in DAP at least). Nothing like a quick glance at the windsock at 200ft to pick up a 32kt tailwind on the ground...
