I'm presently working on the greatest engineering achievement of the 21st century.....The Slotted Tapped Hole.

It's kind of a joke...when engineers make a mistake and clearance holes do not line up with tapped holes. I've recommended to the engineer (as a joke) to use a "Slotted Tapped" hole. I had one young engineer put a slotted tapped hole on a drawing...only to have the machinist come up laughing his butt off.

Putting a couple hundred people inside a Jet and getting the thing to fly through the air and then land safely.

Heres one that seems silly but really amazes me, video games. These days people can link up across the world and play live games with video and audio instantly.

And the slotted Tapped hole, when you get that one done I have plenty of applications I could use it in...

Various medical advances. The engineering involved in that field is often ignored!
