Was watching jets test fly and witnessed a pill shaped Ufo

Parked my work truck near a truck mechanic shop I frequent to take my lunch. while on break, I was watching Boeing test fly 2 F/A-18s in a race track pattern to the East. 15 minutes into my break a pill shaped object shot down from above the circling jets. It was very shiny, the sun was reflecting off of it very intensly. It was suspended in the air for about a minute until it started to move a short distance from side to side very rapidly. By then I had gotten the attention of 3 mechanics I knew to ask if they saw what I did, which they did. They pulled out their phones and tried taking video but could only get still-photos of it. After another minute or so it stopped and remained completely still. The mechanics called over another 2 people to ask what they thought it was. The 2 jet fighters stopped making a race track pattern and came around together low and fast from the south towards the object. Before the jets made it to about 500 meters away from , the object shot like a bullet to the west parallel to the ground. It moved so quick that it would have looked like it just disappeared if we had not been watching it.
