Weather around the time of the accident (02:40 UTC) was:
WIMM 050300Z 15006KT
5000 SCT016 30/25 Q1008 NOSIG=.
Weather would not appear to be a factor - "harzy and calam!" The aircraft most probably departed R/W 23, as per normal operations. It's frightening to consider the final number of ground casualties in that location. Very sad.
