A big colorful oval shaped vessel slowly descending, while spinning and moving forward. No noise what so ever. i could have touched it

I was working tonight at chase at easton office center, when I decided to go for a walk. I went through the back door and walked behind the building.  I was playing with my phone when i saw some thing colorful in the SKY.  I ran to get a closer look, and went to the side of the building.  There's a sidewalk there and i was on it. It was about 10:33pm. Mifflin High School is Behind Chase.   I saw this big ballon like thing. It was colorful, bright spinning and going down at the same time.   I though my eyes were playing tricks on me  but NO!! It was slowly descending.  This white guy saw it too, he just gave me a blank stare.  It landed near Mifflin High school in the field, and I then lost sight of it.  I went back inside. I put all the chase cameras on that spot to see..if it rises again.  But after my shift ended 15 minutes later at 11pm, I drove to Mifflin high school and tried finding the same spot i saw it land.  I hopped the fence and went to the baseball field, nothing was there but the ground was hot and it was like 60 DEGREES outside.  I HAVE NO ((deleted)) IDEA WHAT I SAW..BUT IT WASNT A PLANE OR A HELICOPTER.  I DONT THINK THEY CAN SPIN , GO DOWN AND MOVE FORWARD AT THE SAME TIME.  IT WAS ALSO HUGE.  I should have recorded it on my phone..or jumped the fence at that 2nd and just went to it!!  But i was too scared.  I'm going go to the same spot tomorrow night, with my camera.
