The kamikaze hijackers who began the wave of domestic terror Sept. 11 duped those on board American Airlines Flight 11 into not revolting with a chilling lie: that the plane would land safely as long as nobody made ``any stupid moves.''

``We have some planes,'' the hijackers said in words unwittingly broadcast to air-traffic controllers. ``Just stay quiet and you'll be OK. We are returning to the airport. Nobody move, everything will be OK. If you try to make any moves, you'll endanger yourself and the airplane. Just stay quiet.''

Transcripts of cockpit communications from three of the four hijacked flights were published by the New York Times yesterday, shedding new light on the tempest of carnage and confusion that was unfolding that morning.

But only on Flight 11 could the hijackers' voices be heard - either because one of them hit the wrong button while trying to talk to the cabin or because cockpit crew members had the presence of mind to flick on the radio microphone.

In perhaps the most stunning revelation, the Times also reported that at least two of the commandeered planes were traveling in excess of 500 mph just prior to impact, more than double the speed allowed by the Federal Aviation Administration.

The first transmission from Flight 11, which left Logan International Airport bound for Los Angeles, came at 8:24, 11 minutes after air-traffic controllers lost radio contact with the pilots. The second came nine minutes later, again with the terrorists offering bogus reassurances.

``Nobody move please,'' said the hijackers. ``We are going to go back to the airport. Don't try to make any stupid moves.''

Fourteen minutes later, the hijackers turned the Los Angeles-bound 767 into a massive missile, slamming it into the north tower of the World Trade Center.

Ironically, controllers asked United Flight 175, another flight from Boston that would be used to level the south tower of the World Trade Center, to look for Flight 11 when the latter stopped responding on the radio.

``We have him,'' answered Flight 175. ``Uh, he looks . . . about 29, 28,000 (feet).''

``United 175, turn . . . to the right. I (want to) keep you away from (Flight 11).''

A few minutes later, Flight 175 told another group of air-traffic controllers that it ``heard a suspicious transmission (from Flight 11) on our flight out of Boston. Someone keyed the mike and said, `Everyone, stay in your seats.' ''

Five minutes later - and just seconds before Flight 11 crashed at 8:47 a.m. - Flight 175 deviated from its normal route. As it continued traveling south, rather than turning west, controllers stopped receiving transponder signals from the plane. It was around that time that other pilots flying in the area began to notice the World Trade Center was on fire.

``Anybody know what that smoke is in lower Manhattan,'' asked one pilot.

``(It's) coming out of the top of the World Trade Center building, a major fire,'' said another.

Seven minutes after the transponder on Flight 175 was shut off, a controller in New York asked another unknown controller ``Do you see (Flight 175) anywhere? . . . We may have a hijack here.''

Radar readings would later show the plane was descending at 550 miles per hour when it crashed into the World Trade Center 17 minutes later.

Four minutes after Flight 175's transponder was shut off, controllers received the last radio communication from American Airlines Flight 77, headed from Dulles International Airport in northern Virginia to Los Angeles. Five minutes later, at 8:56 a.m., the transponder signal was lost.

Over the next 20 minutes, controllers and American Airlines officials tried in vain to contact Flight 77. At 9:25, a controller notified the plane heading back toward Washington, D.C. Eight minutes later, the Secret Service was notified and Vice President Dick Cheney, who was in the White House, was quickly ushered into an underground bunker.

At 9:36 a.m., the plane embarked on a 360-degree turn as it passed the Pentagon on auto-pilot. According to the Times, a military transport plane that was asked to ``intercept and identify'' the plane reported it was ``moving low and very fast.'' It slammed into the Pentagon two minutes later traveling at ``well over'' 500 mph.

Transcripts of cockpit communications from the fourth hijacked plane that crashed - United Flight 93 from Newark to San Francisco - weren't released. But crew members were aware of Flight 175's hijacking because United officials sent a text message to 15 United flights saying ``Beware, cockpit intrusion.''

Someone in Flight 93's cockpit later confirmed that the crew received the message.

The warning did no good, however.

A source who heard the radio transmissions between Flight 93 and controllers told the Times that about 9:28 a.m. ``a very noisy sound of a confrontation was heard on the frequency, very garbled, but with some discernible phrase like, `Hey, get out of here!' ''

According to the Times, controllers also reported hearing Arabic being spoken.

Six minutes later, the plane began climbing without authorization and then veered off its normal course near Lake Erie, doubling back toward Washington, D.C. Around this time, passengers began making cellular phone calls from the plane, with two vowing to thwart the hijacking.

Just before 10 a.m., transponder and radar contact was lost. At 10 a.m., a controller said, ``Think he is at 7,500 (feet).''

Flight 93 ultimately crashed in a field in western Pennsylvania at 10:06 a.m., probably because of passengers rushing the cockpit.
