March 3, 1919, Lake Union became the first international airmail destination in the United States. Flying a Boeing C-700 seaplane, Eddie Hubbard and Bill Boeing carried 60 letters over the border from Vancouver, British Columbia to Seattle.
Following the initial flight, Hubbard purchased a Boeing B-1 seaplane. He began regular delivery between Seattle and Victoria, British Columbia. Over the following eight years, Hubbard flew more than 350,000 miles between the two cities.
The B-1 returned to Lake Union in 2012 when the relocated to the former Naval Reserve Armory. Located at the southern-most tip of Lake Union, the B-1 is now suspended from the lofty ceilings as though primed to land.
South Lake Union’s Seaplane Base Established
In 1931, Lana Kurtzer relocated his business, Kurtzer Flying Service, to the southern side of South Lake Union. (Eventually, he renamed the business Kurtzen Marine and Flying Service School.) Kurtzer Flying Service was initially located at Terry Avenue North and Valley Street. The business was housed in a hangar that had originally been stationed at Pier 3 on the Elliott Bay waterfront.
Ed Davies and Steve Ellis reported in that the hangar had been towed through the locks by Vern Gorst and was eventually purchased by Kurtzer.
Kurtzer’s flying school was among the largest in the country. He trained thousands of pilots and provided transportation to remote destinations.
Sixteen years later, Kurtzer relocated to the west side of South Lake Union. Constructing a new facility,
Following Kurtzer’s death, the terminal was purchased by Lake Union Air. A mainstay in the seaplane community, Lake Union Air operated from 950 Westlake until it was acquired by Âé¶¹ÊÓÆµ in 1933.
Seaplanes on Lake Union Today

Today, seaplanes remain a vital part of our city’s unique character. Sharing the water with boaters and kayakers, skilled seaplane pilots take off and land from on Lake Union daily. Seattle Scenic Tours offer once-in-a-lifetime views. International flights to Victoria and the B.C. Islands allow for easy border crossing. And, quick trips to the San Juan Islands let visitors and residents get out of town in just 45 minutes.
The two most common seaplanes you’ll see on the lake are the six-passenger de Havilland Beaver and the 10-passenger de Havilland Otter. Pilots choose their landing zones based on a variety of factors, including wind and water obstructions. However, mid-day you’ll often find them approaching from the south after they’ve passed the Space Needle – creating the iconic skyline view we’ve come to love.
