This is an excerpt from a report made to the Aviation Safety Reporting System. The narrative is written by the pilot, rather than FAA or NTSB officials. To maintain anonymity, many details, such as aircraft model or airport, are often scrubbed from the reports.
My student cleared the airspace prior to taking the runway, and then departed Runway 22 at Springfield Robertson County Airport (M91) in Tennessee, left traffic, turning from upwind to left crosswind at 1,400 MSL. I was making all radio calls over CTAF.
As we started our left turn at 1,400 feet from 220 to 130°, I noted a low-wing airplane 100 feet to my left and 100 feet below me. I grabbed the controls from my student and started to level out and climb and then noted a second similar aircraft flying in formation, which flew directly 100 feet below me. This would put the two aircraft at about 1,300 feet MSL.
These two aircraft did not make any radio calls. I tried reaching them on CTAF but could not reach them.
