Hi, I was flying from San Francisco to San Luis Obispo on April 9, 2021, when a player with the username A609C0AC (Grade 3) was landing. I had pushed from the gate and announced on SFOunicom, that I was Taxing to Runway 28L, Crossings runways 19L, R, and taking off from 28L. I was airborne and clear of the airport, when A609C0AC landed with Very close proximity to me, then initiated a Go-Around Procedure without joining or announcing on Unicom His/Her intentions. I would also like to say, that my weight and balance were very light in The B737-700 aircraft, I was off the runway before the intersection of 1L/19R, 1R/19L.
I can provide photos if needed, but I feel that as a grade 2 player, this was unacceptable from a
grade 3 player. This topic is best with attention to it.
