...and the reason he doesn't get it is because he has no concept of 'real time' !
When a pilot writes up a defect in the part 2, that should take 1/2 an hour to fix, the engineers take the a/c off line for a couple of hours!!!
Sully and co had about 180 seconds to solve a major problem and they did that in exemplary fashion!
Poor old Cosmo would have crashed and burnt in that time and killed himself and a couple of hundred pax!
Better stick with engineering Cosmo, and leave the flying up to the Pros!!
