A Grumman Widgeon 2 engined amphibian has been flying off Lake Union the past few days. We've confirmed it isn't Steve Harvey's N17481 (built 1944) from Kodiak as pictured. Has anyone snapped a picture or recorded the N number? It was sighted in and out of Lake Union Sunday around 7:00 PM and Monday around noon.

It's the test plane for ROW 44, a company that makes in-flight Wi-Fi gear. I bet they're chasing an Alaska Airlines contract. :)
