So, weird flight home (well the FAI-SEA leg) - pilot comes on to tells us our route has been diverted and we'll be flying at a reduced altitude because there are "bombing exercises/practice" occurring and fighter jets are occupying the air space in which we were meant to fly?! On the plus side got some cool dusk views of big mountains super close. (Pilot was no help in identifying them because, as he said, he'd never flown that route before!)
