You may find this surprising, but this happened 3 times in the past 7 days so I decided to make a post. Please look at the screenshot below and note the aircraft with the covered call sign. No he is not departing, he was inbound for landing and was supposed to be on the right downwind - that’s not downwind - that’s interfering with the inbound traffic. Please make sure you observe lateral separation and do not interfere with the traffic on final, otherwise you’ll get a forced vacation spoiler[/spoiler]. Needless to say this guy got his.
And while on the downwind note, if you are not sure what’s right/left downwind, please look at several tutorials here in the forum, don’t make assumptions! Every day I run into someone that doesn’t know what right/left downwind is.
