Series of lights seen while stargazing, possible UFO the length of the Hindenburg.

As I was stargazing outside at 21:25 I saw a series of closely connected lights pass silently and smoothly over the neighborhood traveling West to East. It was visible to me for about 25 seconds but was already halfway through the sky before I noticed it. I first thought it was a shooting star but realized it was a series of individual lights, and positioned as if they were along the sides of a very long aircraft. The only aircraft I could imagine would travel like this (regarding size and flight pattern) would be a blimp the length of the Hindenburg.
