Having been a mech on the 747 for 10 years and still in awe of the beast I have to say that this is one of the greatest videos I have ever seen.
Firstly, cudos to the guy who strapped the camera on the NLG
Secondly, well done for the manual extension of the NLG
Thirdly, well done that it all turned out ok and not a an Investigation
NOTE: Sometimes in life, you have to say WTF I'm just going to do it
