The Experiments Ended …

For many years after 1930, there was a steel tower 200 feet high at St. Hubert’s airfield, which was the airport for Montreal until Dorval was opened.  It was a mooring mast for the R-100, a British airship that crossed the Atlantic arrived at Montreal on August 1, 1930.  It was pioneering a plan to offer an airship service throughout the British Commonwealth.

Eight non-stop flights had been made over the Atlantic by British and German airships when the R-100 made its flight to Canada in 1930.  The trip was carefully prepared, with work on the mooring mast at St. Hubert starting in November 1927.  The venture was financed jointly by Britain and Canada, with Lieutenant-Commander A. B. Pressy of the Royal Canadian Navy in charge of the mooring mast.

The flight of the R-100 across the Atlantic was one of the marvels of the time.  It left Cardington, England, on July 29 at 3:30 a.m. and arrived over Montreal on the night of July 31; it had to cruise around until dawn until it could connect with the mooring tower.  The flight took 78 hours and 52 minutes (to give you an idea of what that means, modern aircraft fly from London to Montreal in less than 7 hours).

The “dirigible,” as airships were called, had been damaged by a storm while coming up the St. Lawrence, but was repaired quickly so that it could go on a demonstration flight.  What excitement there was when it flew over Ottawa after dark, and was illuminated by searchlights from the Parliament Buildings!  It appeared over Niagara Falls at 6 a.m. and then flew over Hamilton and Toronto while people were going to work.

It looked as though airships were going to be the mode of travel for the future, but they were too vulnerable to the elements.  Two months after the R-100 to Canada, the R-100 crashed on a flight to India, killing forty-six people, including every British authority on airship operation.  In April 1933, the U.S. Akron crashed into the Atlantic off the coast of New Jersey with seventy-three lives lost.  The U. S. Macon was another casualty.

The experiments with airships ended in 1937 when the giant Von Hindenburg exploded and burned while landing at Lakehurst, New Jersey.  Meanwhile, conventional aircraft were beginning to span the Atlantic.

For more information of the R-100, I suggest visiting – User: – User: ajor_Dundee. Virtual has made a complete page about it – you must visit, and watch the video too. Another great site to visit is The All great places to start!


  1. One feature of the Empire State Building in New York City, when it was built, was a landing mast for a dirigible. I don’t think it ever was used, if you don’t include King Kong’s brief visit to the top of the building in 1933. LOL!


    • Oh, but I do! I’m glad someone had a camera to take moving pictures of him! Lol. Seriously, that’s interesting. I’m guessing maybe some engineers thought it was worth preparing for .. Cool! 🙂


    • Maybe it’s because they were science-fiction before they were real? Maybe it’s because they look like a big ball. LOL. I’m glad you enjoyed it! 🙂
