Don't be surprised if you hear of similar reports of this from in and/or around the Louisville area over the next 48 hours.
However, you'll need to listen very carefully because noise suppression technology for this pulse-jet engine has dramatically improved.
You'll likely only hear it if it is very near your location, or while accelerating to gain altitude, or perhaps during take off.
Once in surveillance mode, its very quiet and stealthy, especially at night.
Yes, they are going to be watching, listening and scanning.
See you there.
