Captain's log - Stardate 2261.3

Chekov's target practice finally spooked our quarry enough to run. By our readings and Scotty's estimation of the sort of upgrades they might have managed, they're over-taxing their engines. I've ordered a steady pursuit. So long as they don't overheat their systems to the point of an explosion, I've told Scotty and Spock to study the vessel to see if we can cripple it without destroying their hull integrity. I'd like to capture the ship and cargo, but if not, we'll settle for the crew.
