Korean Air first carrier to use drone swarms for aircraft inspection

Great idea. As a pilot and mechanic, it always frustrated me to not be able to see the high-tail hinges and stuff during the walk-around. Here's an example of an otherwise obvious visually-seen problem went undetected by mechanics for quite a while. https://www.youtube.com/watch?v=9NUl46y2OJ4&t=1s

How long will it take before one gets sucked into engine.........

Wow Aircraft inspectors will be working from home far away in low wage countries which will save even more money at a cost to the local communities.......Nice!
