There was a severe thunderstorm warning out. Winds were gusting up to 61 km/h (38 mph) at the time, and possibly much stronger for a brief period.
Could have been a downburst then; I believe we had 3+ crashes related to them in the US about 20 years ago, led to a lot of changes and there have been none since.
Wonder if it might be wake turbulence? Sometimes when there are thunderstorms in the area they really try to cram planes into the narrow windows of opportunity they get.
Regardless, the more photos I see, the more sick to my stomach I feel. It really does not look very good. Ugh.
