I honor all those people on this poor Orion, that was NOT the Galatea
(I just played the mission and: 1. The Eva could not have been there- but maybe it was Eva's ghost? 2. The Galatea was hit from the front and not the side 3. The Galatea made a nice explosion)
No, seriously, it must have been the Galatea, cause there were only two Orions in Deneb, and it definately was not the Bastion.
