Narrative:

After returning from his walkaround in denver; the first officer mentioned that he was approached by a ramper and was told that the forward bins were not locked down and had shifted. The ramper came to the cockpit because he said that this had happened numerous times with aircraft arriving from lax. I called the flight duty manager to report the safety problem with loading in lax. I went to the ramp to talk to ramp lead. He confirmed that the aft bins were also not locked down. I told him to advise his crew to file a safety report. The flight manager asked me if I had any controllability issues during flight; to which I replied no. On reflection on the subsequent leg; I submit the following. At the gate; external electrical was pulled while powering the aircraft without any coordination. There was a lot of banging going on in the forward pit during the loading process. I called the ramp supervisor to the cockpit to discuss the dangers of pulling electrics plus the electrical fault that had occurred as a result. He had been helping with the loading process because it had not been going well. On takeoff the aircraft took longer than normal to become airborne after the pitch attitude had been set. Normally on the B777 it takes about 2 seconds for the aircraft to become airborne. On this takeoff it took about 4 seconds. On the initial descent I heard a bang that sounded like an old aircraft pressurizing. While cruising at 10000 ft at 190 KTS; I felt that something was not right. It may have been that the center of gravity was forward and I was not seeing the normal picture out the window. On landing when the brakes engaged and the reversers came out it was louder than normal.

Title: B777 FLT CREW EXPERIENCES INFLT SHIFTING OF CARGO CONTAINERS DUE TO GND CREW FAILURE TO PROPERLY SECURE THEM.

Narrative: AFTER RETURNING FROM HIS WALKAROUND IN DENVER; THE FO MENTIONED THAT HE WAS APCHED BY A RAMPER AND WAS TOLD THAT THE FORWARD BINS WERE NOT LOCKED DOWN AND HAD SHIFTED. THE RAMPER CAME TO THE COCKPIT BECAUSE HE SAID THAT THIS HAD HAPPENED NUMEROUS TIMES WITH ACFT ARRIVING FROM LAX. I CALLED THE FLT DUTY MGR TO RPT THE SAFETY PROB WITH LOADING IN LAX. I WENT TO THE RAMP TO TALK TO RAMP LEAD. HE CONFIRMED THAT THE AFT BINS WERE ALSO NOT LOCKED DOWN. I TOLD HIM TO ADVISE HIS CREW TO FILE A SAFETY RPT. THE FLT MGR ASKED ME IF I HAD ANY CONTROLLABILITY ISSUES DURING FLT; TO WHICH I REPLIED NO. ON REFLECTION ON THE SUBSEQUENT LEG; I SUBMIT THE FOLLOWING. AT THE GATE; EXTERNAL ELECTRICAL WAS PULLED WHILE POWERING THE ACFT WITHOUT ANY COORD. THERE WAS A LOT OF BANGING GOING ON IN THE FORWARD PIT DURING THE LOADING PROCESS. I CALLED THE RAMP SUPVR TO THE COCKPIT TO DISCUSS THE DANGERS OF PULLING ELECTRICS PLUS THE ELECTRICAL FAULT THAT HAD OCCURRED AS A RESULT. HE HAD BEEN HELPING WITH THE LOADING PROCESS BECAUSE IT HAD NOT BEEN GOING WELL. ON TKOF THE ACFT TOOK LONGER THAN NORMAL TO BECOME AIRBORNE AFTER THE PITCH ATTITUDE HAD BEEN SET. NORMALLY ON THE B777 IT TAKES ABOUT 2 SECONDS FOR THE ACFT TO BECOME AIRBORNE. ON THIS TKOF IT TOOK ABOUT 4 SECONDS. ON THE INITIAL DSCNT I HEARD A BANG THAT SOUNDED LIKE AN OLD ACFT PRESSURIZING. WHILE CRUISING AT 10000 FT AT 190 KTS; I FELT THAT SOMETHING WAS NOT RIGHT. IT MAY HAVE BEEN THAT THE CTR OF GRAVITY WAS FORWARD AND I WAS NOT SEEING THE NORMAL PICTURE OUT THE WINDOW. ON LNDG WHEN THE BRAKES ENGAGED AND THE REVERSERS CAME OUT IT WAS LOUDER THAN NORMAL.
