Anyone know why those two test birds were "retired"? Were they non-flying test articles?
MSN1 and MSN3 are retired, both having completed their respective flying roles in the flight test program. MSN1 is in Toulouse and either has, or shortly will, go on public display. MSN3 is in Seville, and has had some items 'spares recovered' to keep the remaining 3 test airframes flying.
