  • According to the Bureau Of Labor Statistics, the median salary for airline captains, first-officers, second-officers, and flight engineers in the United States is $203,010 as of 2021.

    The big problem is actually in certifying people qualified to take those jobs, which takes additional time and money, mostly to pay for flight time for training. It can take a few grand for just a personal pilot license, but to fly an airline, you need instrument, commercial, and Airline Transport Pilot License (ATPL) certifications, plus increasingly expensive type ratings for the various aircraft you will be flying, a minimum of 1500 hours of flight time, and multiple years at the bottom working your way through smaller regional airlines and courier services.

    You can get through the commercial licensing in 12-18 months and about $40k in flight time and insurance, but that is barely enough to get your foot in the door making $50k a year, and even then, you’re still not allowed to fly parcels or passengers for money. Getting those licenses will take another 18 months and another $40-80k, again, mostly in flight time.

    That said, once you have ATPL, the company will start paying for your flight time, and you will be earning a 6 figure salary. After 5 years or so and about $100k investing in your training, you should be making over $200k, and can begin to recoup those costs.



  • You are trying to solve two different, but related problems, and there are discrete solutions for both.

    One is a personal cloud. You need a secure place to store your shit from multiple users and devices, from multiple networks. You’ll need a mostly static IP and dyndns or your own domain, and certificates signed by a public CA/letsencrypt.

    Then, you are looking for a backup application that supports rsync or sftp/scp over ssh or vpn, that is also cross compatible (Android and PC/Linux). Point this to the service above, and you are good to go.


  • This.

    At some point, you need to be able to quantify the risk to your business before you can do this.

    For instance, if your business earns $10 per transaction, and you perform 100 transactions per second, the difference between five and six nines (313 seconds vs 31 seconds) is $282,000; nowhere near enough to justify the added investment.

    Edit: Important to note that for the first example, these are already enormously huge numbers. Such a business, assuming no holidays or weekends, would be grossing $31.5 billion per year, in the same ballpark as Oracle and Coca Cola.

    So when we say the company is losing 282,000, this is a tiny, tiny fraction of revenue. Even 99.5%, which is almost two days of downtime, would “only” be a loss of 0.5% of all revenue for the year. Sure, this is $157M, but even that would probably not cover the cost of a six nines infrastructure (that said, they could save up to $120M per year by achieving 99.9%, which would be worth exploring).
