Contrails are fairly common, of course,
but I don't remember ever seeing four in the making all at one time before.
Contrail: (noun)
A visible condensation of water droplets or ice crystals from the atmosphere,
occuring in the wake of an aircraft, rocket, or missile under certain conditions.
Also called condensation trail or vapor trail.
