Don't Judge
Personally feel that it is very difficult to judge any Captain's actions based on such flimsy evidence, let's wait and see. Observationally though....
On contract to a fare east airline some years ago, during the Monsoon season, operating DAC/RGN/BKK large jet, we encountered and unbroken squall line with cells joining cells etc about 1 hour after take off - nightmare on radar. 3 crew aircraft, one local one and one, like me, on contract, turned back to our base with full load of pax.
Having previously worked on contract for a (the?) ruthless east midlands based operator, I was concerned about my reception at base. On landing back at departure point, the operations controller merely said "no problem Captain, safety first". No paperwork, no reports, no explanations beyond my one verbal statement. No aftermath. How refreshing that was after the blame culture up the M1.
Refreshingly sensible approach to safety in a much derided area of the world.
Merely an observation, we weren't there, give the Captain a chance to wait of the report.
It is not the third world.
