After the engines are started, the scan is complete, we look out the window and see an engineer (who is also a professional) with a pin giving us a thumbs up. Then we request taxi. That's it. How many people's jobs do we have to do?

Now WTF kind of grammar is that? Even worse than the posters who don't know the difference between "there", "their" and "they're".
