You'd think nuking the derelict where Kane got infected and the creature that killed her crew and friends came from, would be an important enough event for Ripley's character to include it in the movie.
Remember this bit?
EXT. STRATOSPHERE 188
The drop-ship lunges up and out of the cloud layer into
the clear high night. Below, the clouds light up from
beneath from horizon to horizon.
A SUN HOT DOME OF ENERGY bursts up through the cloud
layer, WHITING OUT THE FRAME. The tiny ship is slammed
by the shockwave, tossed forward...and climbs, scorched
but functioning, toward the stars.
