Aircraft is “Giant 3591”
00:28 - Aircraft checks in on freq
04:02 - Controller gives weather advisory
06:19 - Aircraft calls in asking to go on the “west side” of the weather, but controller says he can’t due to arrivals. They talk over each other.
09:25 - Controller calls for aircraft
10:07 - Controller asks other aircraft if they hear any ELTs
Looks like he had to fly through the weather he wanted to go around. Maybe some freakish downdraft.
