Went old school the other day, and took our 707-320 out for a couple flights.
Sadly while on leg 3 I realized, I won't be able to finish out the trip as I wasn't going to have enough flight hours left on the airframe and would have to put her into maintenance after leg 3.
The tail flash was never used on a 707 (they only have it on a 737, 757, and 767), but I'm rather fond of it so I put it together in photoshop and have it on a few repaints I've done. (the actual body I didn't do. Tried, but was having issues with it, so I found this one online for now)
Leg 1: KDAL - PMDY
Leg 2: PMDY - WMKP (pics were taken on the approach to WMKP)
