i saw something different flying

recently i noticed a 3 plume jet stream on a jet at maybe 20,000 ft.
i think this jet was very large, flying approx. west to east over Tempe (Phoenix),AZ.
i would really like to know what it is that i saw,
can anyone help me?
also, the middle jet plume was affecting the right and left stream,
making at least one look ,bowed,.
thank you,
john

Boeing 727?
DC-10?
MD-11?

Possible 3 engine aircraft.

Falcon 50, Falcon 900, Falcon 7X

L-1011

Twin engined aircraft releasing chemtrail

More likely it was the wingtip vortex pushing the contrails around.

Classic example:
