When you live near an airport you don't stop hearing planes but you do get so used to them that you generally don't notice unless something different than the usual traffic comes over. A little bit ago I was driving when I heard something odd departing over me, unfamilliar prop sounds, I was suspecting something experimental. I leaned over the steering wheel and looked up, the first thing I saw was a canard at the front, the second thing I noticed was a pair of pushers out back. At this point I blurted out "Holy #@$%&*! $#!/" and almost crashed the car. I can now check "see a Starship in flight" off the bucket list.
