Flight 1028 passenger: I thought we would crash

* 10 hospitalized on turbulent United flight

Editor's note: Carter Robertson was on United Flight 1028 with his wife, daughter and future son-in-law on Monday. They had been in Hawaii on vacation and were returning to Virginia. The plane encountered turbulence and was diverted to Denver at 2:55 a.m. Eight passengers and two flight attendants were injured.

The plane was close to being full — 187 counting crew — and it was approaching the time for take-off. Everyone was getting settled in for the relatively short flight to Chicago. As we rolled down the runway, I'm sure no one had any idea of what was to come.

As we approached the 37,000-foot mark, the captain turned off the seat belt light. The flight attendants were handing out drinks to passengers some 3 to 4 rows in front of me. The flight thus far, again, was so remarkably smooth that I would say it felt as if we were floating on clouds.

I had decided I would pass on a drink and start with my nap. I had not yet closed my eyes when without any warning — not even the slightest hint of what was about to happen — it happened.

* In a split-second some indescribable force violently sucked the plane 700-vertical feet up and in another split second pushed it down the same 700 feet. ( Care to look up the probability of survival in a physics book')

* How did he know it was 700 feet up & down?

* What does the radar for the weather report say about this?

* Is there any recorded incident in aviation history that even resembles this?

* Satellite imagery readings?

People who weren't buckled in were thrown up, hitting the bulkhead. I was buckled in tight but was suspended above my seat during the roller-coaster ride.

* The flight attendants were also launched up into the plane's ceiling, bouncing off and returning to the cabin floor.

The drink cart was lifted off the floor and landed at an angle against a passenger. One female flight attendant was injured while pulling the cart off the passenger. Pillows, blankets, ice, drink cups and drink cans flew across the plane in every direction. Women and children (and, I'm sure, even some men) screamed.

* The force wasn't just a smooth up-and-down movement.

* The plane was in a constant state of vibrating, shuddering and rolling during this unexpected vertical ride.

* There is no way I can do justice in describing the violent nature of this unprovoked attack upon the aircraft.

I can only say that in the 5-10 seconds this event occurred that many things raced through my mind. In an instant I knew we were all dead, that the plane could not possibly withstand the violent forces attacking it at from every angle.

* As the thoughts continued to race, seconds ticked by, and the plane was now in a 6,000 foot nose dive.

* I quickly realized that the plane had actually survived one of nature's most wicked forces, and now we were racing toward the Rocky Mountains at 400 mph. Probability of survival from this incident? +700 to -7-- ft. and then a 6,000 ft, 'dive'.

Just like in the movies, the noise from the jet engines was increasing in decibels and in pitch. My attention now shifted to the dive of the plane and what was taking place in the cockpit. Was the captain in control?

I don't know how long the dive lasted, but slowly the plane leveled, and the engine noise subsided.

The captain did have control of the plane.

I looked to my right at my wife. We could only shake our heads. It was moments latter before anyone could say anything.

Once the plane was in control, the flight attendants went about the job of assessing the injuries to the passengers. I can't begin to express my sincere gratitude for the clam, professional and courageous manner in which the flight crew handled the aftermath of the event.

It was probably five minutes later when the captain came over the intercom and informed us that due to injuries and possible damage to the plane that we would stop at Denver, and that paramedics would be on hand to treat the injured.

We were in the terminal for about 45-60 minutes when the captain came out and addressed the passengers. The captain apologized for the inconvenience and the horrific events of earlier in the evening. He went on to say that he has flown all over the world for United and has never experienced anything like we did that night.

He assured us that the rest of the flight to Chicago would be uneventful, and he was right.

My everlasting praise goes out to the crew of United Flight 1028. Outstanding job. Outstanding job.

  1. Sounds like the plot of a good novel.  In point of fact, it is: the name of the novel is Airframe, and you might want to read it.  In that one, the aircraft survived intact, but one of the many passengers died; he broke his neck or something when he landed on his head or something.  

    Now, how the heck could anyone calculate the chances of surviving or not surviving such an incident.  Accidents happen.  They probably won't figure out what happened for a long time, if ever, but they'll sure try.  Some weird wind got it.  I had a bad time on a flight to New Orleans once.  It wasn't nearly that bad, but the flight crew was not a bit happy.


  2. Being a military aviator, clear air turbulence is very dangerous, have experienced it a few times but nothing as drastic as this...still whenever I fly, be it commercial or military, I always keep my seat belt fastened.  As far as survivability... guess it would depend on the conditions, phase of flight, type of aircraft.
