An Air Canada plane attempting to land at San Francisco International Airport with 140 people on board was even closer to crashing onto four planes lined up on the taxiway for takeoff last month than previously believed, newly released data and photos show.

The Air Canada pilots on flight 759 from Toronto to San Francisco mistook the taxiway for the runway next to it and flew their jet to just 18 metres above ground before pulling up to attempt another landing, according to National Transportation Safety Board information released Wednesday.

That’s barely taller than the four planes that were on the taxiway when the incident occurred late at night on July 7. A Boeing 737, for example, is 12,57 m tall. An Airbus 330 is ‎16.79 m tall.

A recording of conversations between the air traffic control tower and the pilots involved in the incident offered a dramatic window into the incident.

“Where is this guy going? He’s on the taxiway,” the pilot of one of the planes on the ground could be heard warning the control tower in a recording posted online. The crew of a Philippine Airlines jet behind it switched on their plane’s landing lights in an apparent last-ditch danger signal to Air Canada.

NTSB investigators said they have not determined probable cause for the incident that came within a few metres of becoming one of the worst disasters in aviation history.

The investigators said that as the Air Canada jet approached the taxiway just before midnight, it was so far off course that it did not appear on a radar system used to prevent runway collisions.

Those systems were not designed to spot planes that are lined up to land on a taxiway — a rare occurrence, especially for airline pilots.

Both pilots of the Air Canada Airbus A320 jet were very experienced. The captain, who was flying the plane, had more than 20,000 hours of flying time, and the co-pilot had about 10,000 hours.

The pilots told investigators “that they did not recall seeing aircraft on taxiway but that something did not look right to them,” the NTSB said.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.

  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.

  1. Peter Ashcroft says:

    The runway direction number, based on the 360 degree circle number must be strongly illuminated in darkness hours at the end of, and on the runway, at least the first two numbers. i.e 09 = east to west; 18 = south to north; 27 = west to east, and 36 = north to south.
