The captain seems to be requesting the second approach right after getting a weather update (windshear)from ATC,did not seem to leave much room for the F/O to give his opinion.
Gusty headwinds of up to 36 knots,very low pressure,low mist and rain showers are all but signs of a thunderstorm(s) nearby if not on the field.
During the approach,the first officer voice and requests of confirmations seems to show that he may be worried about what he is seeing and not comfortable with the situation he is in.
The call of go around seemed that of a "yep i told you so",blaze tone.
Vortex,one may blame all the industry,fatigue,bad training,poor handling but unfortunately it seems a case of poor judgement which turned out deadly.
Diverting would have been easier,explanation to the boss as well,and worse case a meeting with no biscuits but a chance to show him the finger and tell him to sit and spin before leaving to better pastures.
Weatherwise,do they use the term CB/SHRA for TSRA?to be honest,one scares me more than the others...
