Speaking of "spoolup," we had a new stud and new IP come back from a weekend cross country late one Sunday night. Their final approach of the night was a low oil ILS. The stud set the power and was trying to maintain glide slope AND on-speed, but was quickly realizing he hadn't accounted for the extra drag of the gear and extended flaps with the recommended 80% power setting and was getting near the pedal-shakers at about 400 AGL (mins were at 200'). So, instead of adding a smudge of power to help out, he elected to pull up the flaps! The IP was fatigued and his head wasn't in the game, so he got the surprise when he suddenly felt the bottom drop out from under him and the velocity vector drop off the bottom of the HUD.
He quickly slammed the throttle forward, scooped out what seemed a very low pass, and landed off the approach. When they got the jet back to the line and hopped out to do the post flight inspection, they both discovered how low they had actually gotten. There were pine cones and pine needles hung in the main gear door fairings and around the tail hook, but no damage (except to their pride, lol).
