The BUFFs are between Prague and Leipzig now, I presume they were sending a message to Vlad.
I guess those were the same two I saw (on FR24) taking off from Fairford. Oddly, FR24 lists them as coming from Kemble, or Cotswold Airport as it now is. You'd think that Fairford, with its 10,000-odd ft runway, might be big enough to be noticed....
