Re: X8T-121: Aerielle
Once the bird-folk Elders had all flown out the front door, SG-X3 had also moved forward to see what was happening, so everyone was standing at the front looking out through the open doorway. Randall was at the front.
The raptor had landed on the nest just above the door, so he was more or less upside down. That allowed him to reach down and through the doorway with his long beak and grab Major Thorne.
Cormac's quick reaction easily hit the creature's beak with a spray of bullets, causing it to let go of Randall. Not quite sure what just happened, the raptor is still perched on the nest when James cuts loose. He can't actually see it through the open doorway, and isn't about to step forward and lean out to get a clean shot, so he simple shoots through the nest. Made of sticks and some sort of mortar, it's not dense-packed--it does let air through, so shooting through it is reasonable.
James has no problem hitting the large creature, but it's hard to tell just how much damage he did. It is enough, at least, to chase the creature away.
FYI: The P-90 is designed to fire in a short 3-round burst in 'normal' mode, which is the setting the SG uses. It can be manually set to fire single round or long burst. Any time you want to use one of the other options, you'll need to state it; otherwise, it's firing in short burst.
