I am very lucky to have been to our engineering base in Cardiff, and although of course not a new build facility, it is absolutely fascinating. To clamber around in the hold, main gear bay and avionics bay of a 747 was something my trolly dolly uniform never thought it would see!
I am glad a couple of people found it interesting...
I am still learning about the private flying side of aviation, but in my mind never had any Learjet type being that large... Although obviously I know it is not as large as some of the other jets...
