I just saw an article in the WSJ about reducing flight crews on jumbo jets down to one pilot, using ground based co-pilots to do the light lifting. I think they are even pondering eventually going with no pilots, while they expect push back from the public over that.  ;D ;D ;D

Some recent landing crashes have been blamed on too much automation, where the pilots do not have the old school "seat of the pants" flying skills (like Capt Sulley did) to react to or even foresee a problem. Landing a jumbo jet is not exactly like hang gliding.

Even worse some high performance combat aircraft airfoils are not even stable so require computer assist to keep pointed in the right direction. 

JR

PS: I wouldn't mind a technology capability for ground personnel to take over and land an aircraft when the flight crew is unresponsive or somehow incapacitated, while the risk of this control being hacked with bad intentions seems very real.

My rule is AP off at the outer marker or FAF (Final Approach Fix) gives you plenty of time to assess the wind direction, gusts and thermals that you will need to adjust for on landing.  It is also good to be fully engaged with the airplane and not just monitoring.

I had a newer younger pilot with me and he saw me do this and asked what I was doing.  I said flying, he said "why would you want to do that if you have the AP"   FML

Not to swerve the topic too far... but blind allegiance to cockpit automation is a Very Bad Thing and is already contributing to aircraft incidents... just like blind deference to senior personnel.

I think we are so far off topic that we've appeared in an alternative universe :-)

A shot of speakers (i think) from ~37 seconds

Jonathan,

The PA shots show large horns with a relatively small compression chamber, the squarish box on the back of the cabinet. The cabinets appear to be a two part conical horn, preceding by decades the now classic rectangular conical horn form "invented" by "Don" Keele in the mid 1970s that he generally used in his designs as he went from company to company.

In early 1992 I developed a 3 way nested conical horn system called the Maltese, the prototype for that system looked nearly identical in form to the Hitler PA. The pictures below show the mid/high portion of the Maltese horn, the bass portion was similar in size to the Nuremberg Rally PA. It is very possible given the driver technology available at the time of the rally that the bass horns had a nested high frequency horn within, though impossible to say for sure without eye-witness accounts or photos from the front.

Maybe my Maltese design was a subliminal PA memory of seeing the Nuremberg Rally in film clips previously  :).

They are Altec 1505s - usually driven by 288s
The entire crew are Lilliputians.

The cabinets look like they might be Clair S4s.

I don't think the large "horn like things" being hoisted into place are actually used-there is no "rear horn", but rather they were just for decoration.

I could be wrong however.
