I was travelling in my ram truck, heading west on route 1604 near universal city. i saw an orange aircraft that appeared to be a biplane. i thought it was going to land at randolph afb. i put on my glasses for a better view. i then recogised it was too large to be a biplane but it appeared to have two parts to it. both oval to cigar shape but the two parts seemed connected, one on top of the other. the traffic in front of me slowed down in the right hand lane as i think we were all looking at the object. it appeared to hover but then changed direction and speed and headed northwest. it disappeared into the clouds. the weather was great as it was a sunny day.
