Sunday afternoon at the listed date and time I was about 25 miles North of Sierra Blanca Texas, which is at about I-10 East/West mile post 106 and about 25 miles South of Highway 62/180. I observed an object fly over the house and do not know what it was. The object was white/silver colored, very large, headed from the West to the East, made no noise and left no contrail. The object was followed by a jet airplane I would guess about 5 miles behind the 1st object. The jet did make a lot of noise and did leave a contrail. The first object was cylinder shaped and had 1 wing sticking out the right side. Other witnesses stated the one wing was retangular shaped and one other stated it was triangular shaped. All stated the 1st object was much larger than the jet. The jet was moving very fast but was not gaining on the 1st object. I did observe the object through field glasses but was not able to get a good look at it. We do not know what the 1st object was and were wondering if anyone else saw it or knows what it is. The other witnesses had a better view than I did and all stated there was no tail rudder or elivator like on an airplane. I did not notice a tail section either. I did see a tail section on the jet that was following. If you know what it was we would like to know and if you had a picture of it or a drawing we would like to see it. I do not recall seeing any other air traffic and there were no other contrails in the sky and the sky was pretty much cloudless. We were on the South side of the object and were looking at the right side. One of the witnesses had stated to me that he had see an object about an hour earlier that afternoon and was not sure what it was. I walked outside the barn and looked up and saw the 1st object flying overhead. I asked him if that was it and he said it could be, ran and got the field glasses and advised the other witnesses. I watched the object and looked at it through the glasses and eventually lost site of it as it headed East. I heard and then saw the jet about 30 seconds after seeing the 1st object.
