Yes, perspectives can be decieving....not just of contrails, but in all aspects of vision.
For example, how long is your typical human arm....the total length ? ....measure it.
But photograph that arm "pointing at the camera".......measure the resulting photo that that way, and you'll get get an in-accurate figure.
not the best example, but basic one-point perspective......
