Ok basically the title explains it. Tell us what the wildest thing(s) you did in a flight simulator... include the formal game name, plane/helicopter, weather, and other details...
Game: Microsoft Flight Simulator 9 (AKA "A Century of Flight", "Flight Simulator 2004")
Airplane: Boeing 747-400, the world-travels variation
Weather: Building Storms preset
When: Today, at about 5PM EST
Well, I was flying from Miami, Florida to Honolulu, Hawaii, finally to finish up in Narita (AKA New Tokyo), Japan. So, I was most of the way there, about 400nm from Honolulu on an IFR flight plan. I was up at 45,100 feet (max operating ceiling) doing about Mach 0.85. I flew quite a bit already, using time compression (16x) after canceling my initial IFR flight plan. I cancel the flight plan and go up about 10,000 feet to FL451. I put in the max speed they recommend; Mach 0.85 for cruising. I notice that it will smootly go to Mach 0.86. I decide to push the plane as much as I can (mind you I was on the hardest mode)... Mach 0.93... 0.94... I canceled out auto-throttle, pushing my throttle to the max. I hit at most Mach 0.95.
Well, I ended up about 300nm away, I slowed to Mach 0.85. At 250nm away, I requested an IFR flight plan to Honolulu for FL250; I slow down a bit and drop to that altitude, though not before hitting my own personal max-speed in the process. So, I have auto-throttle on, it's about -26*c outside. My pitot sensor decides to quit on me, while I am descending at 1800ft/min. So, I speed up rapidly; I hit mach 0.94, no stress warning. 0.95, still no stress warnings. 0.96, STILL no stress warnings. I end up at Mach 0.97 (topped out there) and came to altitude (FL250). I start taking some directions, and I get bored very quickly, about 200nm out.
So, I decide I want to do some funny stuff... barrel-roll the 747 again. Well, I cancel out all autopilot functions and take manual control of everything (my pitot sensor is still out). I pull the stick to the right, pull back on it, and rotate it to the left (to keep my nose above the horizon). Well, here came the problem... going at such a high speed (about Mach 0.85), there was way too much drag; the air started to act upon the 747 quickly. I lost all control; sinkrate! I immediately spiked to about mach 0.95, lose all forward momentum.
So, I am now sinking quickly... I remember back to what I usually do (and lose control), so I did something else (apparently the correct thing to do?). I pointed the nose down, cut engines, deploy full flaps, and open up the spoilers to get my airplane back into a controllable situation. Well, I managed to recover, about 20 seconds later, nearly breaking the speed of sound in the massive 747-400. I ended up at 1,770 feet above the Pacific, doing about 280kias. I slowed to 240kias (the speed limit below 10,000') and started getting radio messages from ATC; I was over 20,000' below my assigned altitude of FL250. I have the flight saved and running on my computer... I am currently at about 18,000' and climbing at a standard 1800ft/min, doing about 340kias to FL250, where I will return to Mach 0.85. Oh, my pitot sensor corrected itself during the maneuver I did... it turns out I did what seems to be a fighter-plane maneuver for (a) rapidly changing direction, (b) gaining excessive speed, (c) losing massive altitude, and (d) avoiding anything that could be following me. I did it all in a huge 747-400 without ever getting the Overstressed notice and only once getting the Overspeed notice (during the fall, of course)!
