Here's a Fenrir from a couple of weeks ago
And my forming up on two F-15's and an Su-27 on a free flight server yesterday. The guy with the smoke was doing his own navigation thing I think, the other two and then myself all formed up on him spontaneously. I buzzed them from a steep dive at Mach 2.0 a few times before that
The two other planes disappeared later, I followed the lead F-15 all the way to his landing airbase. I never knew the Mig-21 is HALF THE SIZE of an F-15!
