Dumbest thing you ever did in flight.

OHHH I win this!!

I was flying my Learjet 45 from San Franscisco to Vegas. It was visual weather but I selected IFR flight just so I could be vectored to my
destination and then chose a visual landing. It was a great flight, perfectly satisfied passengers and all was going well. ATC gave me
directions to begin my decent to my destination had me turn onto the track for straight in final. I chose a visual landing and started my set-
up (I was still quite a ways away). I got to about 1700 AGL and ATC cleared me to land straight in visual. At this point in time I'd like to
mention that I'd been flying the entire thing using AP. When I was cleared to land, I began to disengage a few things on my autopilot and
dropped gear and flaps. Then of course, my FO comes on and tells me that my gear isnt locked down...great. I quickly disengadge my
flight director and declare emergency. I pull throttle, touch down and brake. Something is wrong, I'm losing runway and not slowing
down! My brakes are full and, without really thinking, I put on the emergency brake and set up the speed brakes. I'm starting to slow, but
by the end of the runway theres only one thing to do. I slam the left pedal forward a begin to execute a perfect powerslide with my Lear.
The plane skids to its side, The weels get closer and closer to the end of the runway..and the ditch happily awaiting my arrival. I hold my
breath, keep the skid going and the plane grounds to a halt. I'm off the runway, but managed to avoid the ditch by just a few feet. I open
doors, begin to evacuate the passengers and thatnk God that my gear held through it all. It was only then, when I began to shut down that
I noticed the 2 lights on the AP panel. The first was the autopilot master switch. The second was the speed hold button, holding my
plane at a speedy 250 knots and still trying to propel the plane forward. I shut the engine down and think back. I realise then that when I
declared emergency and shut down my AP, I never hit the master, only the flight director. Of course, this means that I missed the speed
hold button and touched down at my 250kts cruise speed.

Ya, not too bright
