Why not an enroute landing in such condition?
Because the whole aviation industry would then come to a grinding halt.
Actually a nice video of TX activity at night . I once flew parallel to a line of storms across India during the monsoon season. Line stretched for 150 miles, with a nonstop display of fireworks lighting up the clouds from within . Spectacular, and beautiful to see at night . However, glad I wasn't heading north/south and having to make a decision where to penetrate the line .
Just for the benefit of the uninitiated , the guys in the video were doing a pretty good job of deviating around the cells. Look at the radar (as previously mentioned, worked great on the 744 ) and you see clearly defined gaps . Industry standard says to avoid cells at altitude by 20 miles , but we know that is not always possible....
Nevertheless , looked like a smooth ride on the flight deck , apart from a brief spell of (usually expected) rain/chop at the end as they cleared the edge of the system.
I bet the champagne continued to flow in First Class
