Hmm it is possible that it was UFo. We people think that they dont want to be seen however... if theres any recorded ufo its always slow or its not
moving. Maybe ufo's are so fast that our eyes cant see their movement. If they come from far far away they must be even faster than light i guess. If
it was ufo then i would say: they were observing something. if they would be travelling it would be probably impossible to see them...
There is a N.A.S.A. balloon base near where I live in East Texas and that is a weather balloon. The University Of New Mexico runs the base here and I
believe there is one there as well.... They look awesome in the evening sky.
