The overall trim system now appears to be under scrutiny by several XAA's.
Also, what is more likely in the final dive of both crashes:
Pilots pulling with as much physical strength as they can muster to avert certain death did not think to also apply more than 2 brief blips of ANU trim to help...
Or
For the same reason manual trim is impossible in specific conditions, so is electrically operated ANU trim...
?
Seems to me that once the stab due to MCAS or runaway trim reaches a certain point it is unrecoverable without the old roller coaster manouvre few have been trained on or practiced. And possibly not just the Max.
I hope I am wrong of course, but this story may yet have further twists and turns to come.
