Re: B737MAX Grounded Worldwide

Well I think there have been incidents in North America regarding MCAS but no crashes thankfully, I would chalk this up to the US, Canada, Europe etc. have pilots whom started on Cessna's and learned worked their way up to the airlines or were military/air force pilots. They know how to fly first a...

Re: Is it time for Cockpit Video to aid in crash investigation?

I'm 52 and I was well into BBS sites while in the Army in the mid 1990s.

I was a calibrator. Jet Cals being one of my least favorite items to calibrate.

If you can't support such an appalling accusation against the NTSB, then you really should quit posting it.

Re: Is it time for Cockpit Video to aid in crash investigation?

How about cameras that are forward somewhat so that they just show the IP and maybe the hands of the crew? We could see the instruments and we could see what the pilots are doing regarding flying the plane, but we could not see the whole cockpit. I think cameras could be set up that way.

There is a slim chance the MAX won't fly again. Boeing need to come up with a plan B to downgrade the frames already built and those in service back to NG standard.
