NAT TRACK E UPSET 27th SEP
 

Listening on 12345 on a random track, almost overlaid on E, heard that an "aircarrier" had an upset.

Wing dip 45 degree and a climb of either 1000ft or a 100ft rate of climb.

Great consternation from the other guys in the area at same or similar levels.

Is there any more accurate and learned information available. ??
