One flight just took off (in the wrong direction) 5 minutes ago, so the airport seems to be functioning now. IFR long-haul flights need at 90 minutes reserve at destination. I've been here in Simpson Bay and those rainclouds are just nimbostratus rainclouds and no CuNim (thunderstorms) which might threaten flights. I wonder if SXM's systems might have gone down and prevented arrivals? Although they could have done a daytime VFR landing given the benign conditions, perhaps it was something physical to do with the runway?
