On the 13th, an aeromedical evacuation aircraft was inbound to MPA from Chile, eta about 2245Z (presumably based on the TAF issued 1924Z - this was before the recent change where MPA extended the closures to include 1 hr before and one hour after any forecast 56//// conditions).
At 2226Z, an amended TAF was issued, with the forecast 560003 now from 2200Z. The aeromed was denied permission to land, despite the actual conditions remaining OK, and had to divert to Argentina.
Throughout the period, there were no gusts reported in the Actuals, and no SPECIs issued. Despite a peak reported wind of 19kts, and a large part of the period reporting less than 5kts, the airfield was closed to landings and departures. I have operated aircraft into Mount Pleasant for over thirty years. The dangerous rotor streaming conditions do NOT suddenly appear when the basic wind is 5 knots.
This is "safety" gone mad!
