 		#LOC_OPT_opt_vtol_wrapk2_title = OPT-E WarpJet FVT-K
 
 		#LOC_OPT_AAengine_desc = The ARI Engine is a unique, small profile engine. It uses OPT's S.C.O.O.P. technology to achieve high efficiency within the Atmosphere. At the same time it act as a normal chemical propulsion engine in space.
-		#LOC_OPT_engine_darkDrive_desc = After decades of research and experiments on the Mystery Goo, scientest are now able to refine it into 'Dark Goos' and put it in good use. This new type of goo feeds on rocket fuel and produces something much more interesting. Even though Dark Goo is no longer fictional, the failure rate of the refinement procedure is still extremely high, making Dark goos one of the rarest and most expensive substance known to Kerbal kind.
+		#LOC_OPT_engine_darkDrive_desc = After decades of top secret research on the Mystery Goo, kerbal scientists finally discovered, or produced, what was fittingly called the Dark Goo. Following this breakthrough, they have only begun to find its uses in containment, catalyst processes and combustion, and with those, the ability to produce a curious new breed of ultimate engine, the Dark Drive.
 		#LOC_OPT_j_linear_aerospike_desc = This linear aerospike engine is fitted for the J fuselage. It certainly packs a punch for its size.
 		#LOC_OPT_opt_mk2_engine_short_desc = A mysterious atmospheric engine that offers great thrust at thin atmosphere.
 		#LOC_OPT_opt_nebula_engine_desc = The nebula engine is the ultimate engine to achieve SSTO. It's a shcram jet equipped with a massive Super Condensation Optimized Output Propulsion unit. It scoops up various inert gases in the atmosphere. Once optimum speed and altitude is reached, the engine ionize and super heat the gases in its chamber, the resulting plasma is then expelled together with the hot gas from the shcram jet. The result is a brilliant blue plasma 'after burner', which will give any spaceplane a powerful punch into space.
