Episode 10  What Did You Know, When Did
You Know It?
1.       Numbers: last four years: +97,000 to reach 413,000 overflights annually

2.      Numbers: proposed new increase: +80,000

3.      The tip of the iceberg  the Watergate standard applied to your knowledge as of
September 11, 2018, that aircraft noise associates with:
- High blood pressure/hypertension; cardiovascular disease; heart attacks; stroke; stress;
sleep disturbance; cognitive impairment, arterial hypertension, myocardial infarction
- Worse at night  increases stress hormones and vascular oxidative stress, which can
lead to endothelial dysfunction, arterial hypertension, increased risk of atrial fibrillation
- Worse for elderly living near airports


- Worse for children and schools near airports


- Automated changes in flight operations are making it worse
