Yes this really is weird and has happened three times to me now. I have searched the forum but not found anything (although the Avsim search engine leaves much to be desired). On three occasions now I have landed the 737NG-800, which from 1500 feet AGL, were in full manual control - the autopilot and A/T were both off and flaps set at 30 with gear down. Autobrake was set to level 3. After t/down I hit F2 to get reverse thrust and the reversers activated ok. When down to about 60kts I hit F1 to idle the throttles and applied manual braking, so disconnecting the autobrake. But the plane kept going and did not appear to be slowing. It was certainly too fast for a taxiway turn-off, even the high speed ones. The first two times this happened I ended up crashing on the ground and as is the case with FS you cannot then review what might have been wrong. The third time I was able to steer the plane off the end of the runway and on to the grass and it gradually slowed down but not in response to anything I was doing. When it came to a halt I used FS Recorder to do a replay and watched inside the cockpit. Sure enough, the A/P and A/T were both off after 1500 AGL, flaps were at 30 and the gear was down. The landing was fine if a little firm but otherwise quite normal but Madam NGX just wanted to keep rolling as I've described above. The only common factors between all three incidents is that they occurred at airports with scenery by UK2000, thr first time at Belfast Xtreme the other two times at Gatwick Xtreme. I mention that but really cannot see how the scenery would influence what happened. Anyone else have anything like this happen? My rig, btw, is Gigabyte board with Core2 Quad Q9650 not clocked and 4GB DDR2 RAM/Geforce 9600GT 512MB. Iain Smith
