I figure this is more of an ops question so I am posting it here.
A couple of days ago early in the morning, during gym class, I saw an American 727 fly over, close enough that I could identify it. The location where I saw it is about 35 miles NW of PHL. In the 13 years I have been living here, I have never seen a commercial jet fly low enough in this area that I could identify it.
Similarly, after school, while walking home, I saw two sets of contrails. I could barely make the type (737) on one, but no scheme, and nothing on the other as they were both directly overhead.
My questions are: Why was the 727 so low (it wasn't terrain following, but it was low), and how high do planes need tp be to produce contrails?
Thanks for your time and answers.

The Bunts One Arrival into Philly has aircraft crossing Bunts intersection at 8000 feet. This intersection is about 35 miles NW of PHL. If you think the 727 was lower than 8000 msl then perhaps it was a precautionary or emergency situation.

Last year I flew out of LAX for Chicago on a DC-10 and about 30 minutes out over the desert the cabin filled with the smell of a hydralic fire. The captain made a steep decent while dumping fuel to ge us below 10000 ft (no oxygen required for passengers) and ready to land. We headed toward Edwards AFB and the hot smell dissipated some what. The Captain told us that we were on a backup system and that we were going back to LAX.
We flew through the Cajon Pass about 1000 ft above the I-15 freeway and into the LA basin were we stayed at a few thousand feet till we made our safe landing. I often wondered what the people on the freeway thought when seeing a DC-10 flying that low in the pass! We could actually see the people in the cars and trucks looking out at us.
