It was a tough weekend for Houston’s residents, and for the first responders. The 911 service received some 50,000 calls. Houston’s airports were closed, but Southwest Airlines airlifted about 500 people out of Houston Hobby’s lights-out airport before sunset, on five special flights, so that they were not stranded at the airport. The flood water filled up all the lower-lying areas, and also reached downtown Houston. Resources are pouring in from everywhere to help; even from Seattle. A responder team of 17 people left today; they will drive 36 hours straight to make it to Houston to also go and lend a hand. Check out the New York Times articles; they took the paywall down so that everyone can access their coverage.
