Even if those drones and cruise missiles were flying nap of the earth they could have been detected. But the Saudis suck at both the offense and the defense, so there’s always that to consider... ;-)

Time to open a manual perhaps? Boeing tech support?

It’s very hard to “see” anything below about 1,000 feet unless you have been tipped off and specifically looking.

Ground observers in Kuwait reported sightings below 750 feet. Given the flat terrain, lack of ground radar, attacking in a swarm, they could be missed.

We have a number of IR sats that would show the hot exhaust tracking after the fact, when the data is uploaded and analyzed, which takes time.
