surfinn pretty sorry stuff there. I agree pretty poor sportsmenship as well. If this had happened to me I'd be hot!!
As to "who" was flying the plane. Just remember that a callsign is to the account and not "who" may have been flying and shooting at the time. We all know that visitors can sometimes gain control and fly, just saying. Never the less the callsign owner is responsible for the actions. This is a squad CO issue that I would like to think will be dealt with internal to that guys squad, and quickly. Otherwise there is likely to be problems with other squads wanting to coordinate and work together.
Not something we see very often and hopefully an isolated incident.
