8. Unmanned aircraft - 1964

The first unmanned aircraft with the name D-21B.

In order to carry out reconnaissance missions in China in 1969 and 1971, the world's first unmanned aircraft was invented as D-21B. However, the invention was later stopped due to the high failure rate. Along with that, President Nixon has come up with a smarter way to capture images from satellites.

9. Internet - 1969

The Internet had its beginnings in 1969.

In the 1969s, engineers from UCLA sent to Stanford Research Center from " LOG" via a newly invented network called ARPANET, which was the beginning of the internet used today.

10. Mobile phones - 1973

The first phone in the world was born in 1973 and weighed over 1kg.
