The alarms that go off, on pretty much all retractable-gear aircraft, when wheeels are retracted at landing altitudes are effing deafening.
I recall sending airplanes around for no-gear efforts at landing. It's not routine, but neither is it as rare as one might expect.
One episode in the log of "Wheels-up landings, Always comes to mind.
A 'State of Illinois' Twin Cessna actually did land 'no-wheels' arrival at night. The Pilot was a real -----, and was racing to the runway with inbound F-4s. His manhood was offended cause I planned the fighters (who, at 30 miles out were behind him by 5 miles or so) to be 'Number one' for arrival, based on speed and performance expectations for each aircraft; I had them both sequenced for the Long runway on parallel paths. The Twin Cessna Pilot decided he would keep his speed up, balls to the wall, to prove to me that he should have been #1.
When I saw him keeping up with the F-4s (unexpectedly) I realized what his plan was, and I changed my plan to accommodate his. I broke him off approach to RW22, and cleared him to land on a crossing Runway, RW30, and to 'Hold Short for arriving Jet traffic landing straight-in on RW22'. This really hurt his fee-fees, and he continued at uncharacteristically high speed.
He flew his craft beyond normal performance levels by waiting to extend the wheels, in order to stay slick, fast and hot, so as to avoid normal traffic pattern speed reduction associated with 'Drag" that wheels-down' configuration required for landing. In doing so, he had to ignore an ear splitting "wheels-up" alarm horn in the cockpit. Ultimately, he 'landed' without gear and did $ 100K plus damage to props, engines, and fuselage. No injuries, thankfully.
I couldn't help myself, and I called the report in to the local Newspaper.
The story of his "race with F-4s" came out next morning, detailing the wheels-up landing, and the unusual circumstances leading up to it. The paper carried it front page of "City News", the second section, above the fold.
That, as I recall, was a good day.
