Possible re-con by an low flying object with lit row of lights slowly traversing a navy runway then zipped away.

Out door movie being shown along side the landing strip,at approx. 9pm the audience shouted to stop the movie. Everyone watched an object with the equally spaced row of round white lights moved slowly down the lenghth of the 10,000 foot runway then quickly zipped off out of sight.  We called the base authorities who contacted the air force project blue book, it was written off as a flight of seagulls in formation  flying down the runway and the runway lights reflecting off them.  But the thing about it was, the runway was inactive, so the runway lights were off.
Date is approximate.  PD
