So we have explosive device that passes through airport security scanner. And can be made at home by dedicated individuals... What are the implications for air travel?
There are likely no implications for air travel. At least I always assumed that advanced state actors can make explosives that are undetectable by airport security scanners.
I don't think it passes through modern American scanners--they can theoretically discriminate plastic explosives (and presumably detonators) from water, though whether it gets caught is a matter of TSA competence.
Part of the reason why this is one of those "cat out of the bag" type things.
I wonder how many duds are currently being processed by Hezbollah right now.

The threat vector OP refers to is a terrorist packaging this into e.g. a laptop.
Or they tested them on their airport security scanners (and the question of why this group needs an airport security scanner to test things on).
Either way, the implications for air travel are not all that great!
