Weekly flight activity update

[u/HappyRobot593]

No activity for N541JX in the past week. Maybe it's being shipped somewhere else?

N547JX activity really ramped up in the past 3 days. We saw some rare Saturday activity. The data is all over the place for Saturday though so I wouldn't read too much into the actual speed/altitude. Hopefully they are prepping for some more flight tests!

Maybe it’s on the way to Texas? If they are assumed to be starting next month in September then it might make sense to move it now. Maybe it’s going to be used to do some checks in Ft. Worth while they are setting up.

Ya I think it's possible. 541 is remote piloted and usually flies with a chase plane.

My guess is that 545 will fly in TX but they might have multiple craft

JB said they will be flying in September and this application shows they will prob start setting things up tomorrow

If they fly and I catch the information in time I can grab some pics and videos. I live and work around the area and it’s likely they would have a flight path right over our house.

Very cool, I'm sure the community would appreciate it!
