tl;dr Only 3.5 helicopter landings happen at Children's per month on average during quiet hours (10pm - 8am), that comes out to roughly one every 8.7 days

I did a little digging to get a clearer picture of how many and how often helicopters are landing at Children's hospital.

Hospital landings began in September 28,1992, so it's safe to say most people who live there moved in AFTER the helicopters started landing at Children's hospital.

The data is from this pdf: semi-annual report to the community summarizing emergency medical helicopter landings at Seattle Children's Hospital

Here are the between 10pm-8am landings for July - December 2025.

July: 3

Aug: 6

Sept: 2

Oct: 3

Nov: 2
