If you missed the start of Alien Secrets, Flight of the Kestrel book 2, here is the link. To help your imagination, my idea of John Blackwell is the actor Brian Cox.
'We need to discuss two things,' Darrow said to his senior officers. 'Battle damage and this man Tanu. Commander Blackwell, your report please.'
Blackwell raised an eyebrow at the unexpected mention of Tanu. 'Aye sir. Kestrel sustained some serious, but not critical damage,' Blackwell said. 'Most of the damage has been quantified and repairs have begun internally on non-critical systems. Without landing somewhere we will have to suit up and go outside to repair the thrusters and the sensor array, but the rest we can fix from Engineering. The hull plating will have to wait. I've got Stubbs checking the inventory for spares, but I think we have everything we need. Engine output is reduced to half power, but we need to shut down all engines at some point.'
'Any idea when we'll have full warp drive?'
'We're carrying out a full survey of the engines now. I'll have the results for you in an hour.'
