Attempting to Ward off Cyber Attacks

Since the Antiplanner is vital to national security, I was disturbed to learn that people with .ru domain names have signed up and attempted to take control of this web site. In fact, there are nearly 10,000 .ru users.

A few years ago, I realized that nearly 50,000 users had signed up, and while it is flattering to think that many people were interested in my pearls of wisdom, I was disillusioned to discover that most of them were spammers. At the time I searched in vain for a way to delete those users in bulk without deleting any real users. Instead, I installed a captcha system that supposedly would prevent bots from signing up.

It didn’t do a very good job as the Antiplanner had 156,600 users yesterday. I found a WordPress plug-in that would delete users who have never left a comment, so I tried to use it. It would only let me delete 1,000 at a time, and after deleting 10,000 the system broke down.

Unfortunately, I suspect that it also deleted some real users. If you have been unable to log in, you may have to sign up again as a new user. Please accept my apologies. If anyone is a WordPress expert who can recommend a way to delete spam users, please let me know.

Airlines: Our #2 Source of Mobility

Airlines carried Americans 77 percent as many miles of domestic travel in 2021 as they did in 2019, according to data recently released by the Bureau of Transportation Statistics. International air travel was still far short of pre-pandemic levels, being just 29 percent of 2019 numbers. The 578 billion miles of domestic air travel was about the same as in 2013, while the 1,743 miles per capita was slightly more than in 2003.

U.S. airlines are, or should be, the envy of the world. They carry Americans far more miles per capita than airlines (or, for that matter, railroads) of almost any other country. Airport infrastructure is in excellent condition: as of 2020, 85 percent of commercial airport runways were in good condition, 13 percent in fair condition, and only 1 percent in poor condition. U.S. airlines’ safety record is second to none, experiencing just 14 fatalities while carrying more than 7 trillion passenger-miles since 2010. And airlines do all this at a profit: while some companies have lost money in some years, the domestic airline industry as a whole earned a profit in every year since 2010. Continue reading
