Dora-9 it was a post maintenance flight and yes we were flying without the benefit of hydraulics to the controls. In no way am I claiming to be an ace but LS certainly is as he has had to turn stab trim switches off therefore his knowledge of the 737 (and Airbus apparently) is absolute although he has never flown either and he still does not understand what MCAS does. He also doesn't seem to understand the difference between aerodynamic difficulties worked through on prototypes and pre-production aircraft that are subsequently certified and documented by the authorities and the MCAS system that was installed on an existing design with minimal oversight and deliberate obfuscation by Boeing. Boeing even went so far as to make a warning light that told the crew MCAS was operating an optional extra! I'm sure Sully is keen to chat to LS so that he can glean some crumbs of aviation knowledge that might fall from LS rather bloated table.
