???pax,
I do believe you are correct. I looked at his profile and his name came up.
So, if Hamrah is reading this...let me first say that I love the video; thanks for agreeing to do it. You were very thorough in explaining all the systems and got me more interested in the 737. Perhaps as the chief pilot (at that time) you know something about these trim wheels that others are not aware of?
It's not a nagging question, just one of interest. Again, great job on the video!
Cheers!
