Narrative:

Departed gate at XA33. Return to mex gate at XB05. As landing gear was being retracted after takeoff, loud vibration could be heard and slightly felt, unusual for gear. I felt there was a problem, but waited for word from cockpit. No recycling of no smoking sign (signaling 10000 ft). Heard signaling (beeping) of an alarm. Called 2L/right door flight attendants to see if they heard it -- negative, the sound was coming from cockpit. Then aircraft pitched aircraft right, passenger made sounds 'oh,' 'wow,' then aircraft pitched aircraft left. Out of forward entry door peep hole, could see 'green.' I knew it was mountains, because of tree outlines. Unusual, because jump seat is too low to clearly have visual access outside without standing up and looking directly out of hole. Then cockpit called on interphone stating problem of pressurization, returning to mex. He would make PA to cabin. I made 'prepare for landing' PA to cabin, after telephoning crew on interphone. Passenger visibly shaken (because you could feel aircraft was not flying correctly) but very relieved returning to mex. Several passenger declined to return.

Original NASA ASRS Text

Title: FLT ATTENDANT RPT, B757, MEX-DFW, CLBOUT, PRESSURIZATION PROB. RETURN TO MEXICO CITY FOR MAINT.

Narrative: DEPARTED GATE AT XA33. RETURN TO MEX GATE AT XB05. AS LNDG GEAR WAS BEING RETRACTED AFTER TKOF, LOUD VIBRATION COULD BE HEARD AND SLIGHTLY FELT, UNUSUAL FOR GEAR. I FELT THERE WAS A PROB, BUT WAITED FOR WORD FROM COCKPIT. NO RECYCLING OF NO SMOKING SIGN (SIGNALING 10000 FT). HEARD SIGNALING (BEEPING) OF AN ALARM. CALLED 2L/R DOOR FLT ATTENDANTS TO SEE IF THEY HEARD IT -- NEGATIVE, THE SOUND WAS COMING FROM COCKPIT. THEN ACFT PITCHED ACFT R, PAX MADE SOUNDS 'OH,' 'WOW,' THEN ACFT PITCHED ACFT L. OUT OF FORWARD ENTRY DOOR PEEP HOLE, COULD SEE 'GREEN.' I KNEW IT WAS MOUNTAINS, BECAUSE OF TREE OUTLINES. UNUSUAL, BECAUSE JUMP SEAT IS TOO LOW TO CLRLY HAVE VISUAL ACCESS OUTSIDE WITHOUT STANDING UP AND LOOKING DIRECTLY OUT OF HOLE. THEN COCKPIT CALLED ON INTERPHONE STATING PROB OF PRESSURIZATION, RETURNING TO MEX. HE WOULD MAKE PA TO CABIN. I MADE 'PREPARE FOR LNDG' PA TO CABIN, AFTER TELEPHONING CREW ON INTERPHONE. PAX VISIBLY SHAKEN (BECAUSE YOU COULD FEEL ACFT WAS NOT FLYING CORRECTLY) BUT VERY RELIEVED RETURNING TO MEX. SEVERAL PAX DECLINED TO RETURN.
