here’s the cutdown play by play of what happened in the traffic control log
The Whiskey Barge enters the Inara Equatorial Space Port Controlled Space, contacting Inara Approach, who advise them on surface to space threats, and allow them to enter the controlled space, and tell them to contact Inara Main (ground control essentially)
The Whiskey Barge acknowledges all
Vessel in distress, identified as The Whiskey Barge, struck by the railgun sabots (high velocity debris)
Inara Main asks for damage, soul contact (people on board) and how much fuel they have. The Whiskey Barge is able to get out their initial damage report, along with how many people they have onboard, but the pilothouse (bridge) is struck by another railgun sabot
Inara Main tries to regain contact with The Whiskey Barge, but is unable to. Inara Main contacts Operations One (emergency services) to respond to the incident. Operations One responds.
The crew of The Whiskey Barge evacuate as Operations One arrives on site. The railgun sabots punched clean holes through the drive bay, forward fuel tank, and pilothouse. Infrared sensors also see the fuel lines beginning to catch fire
