The basic steps are:

1. Register a domain of your choice
2. Select who you are setting up your email with (plenty of different providers, Zoho has a basic free plan that would be suitable for a single domain and only a few users at most; Google, outlook etc. also sell services for custom domains)
3. Configure the DNS records for your domain to whatever your chosen email provider says (MX records to point to the mail server and some records for DMARC & DKIM to prevent your email being spoofed)
4. Test it all works and start using it

I’m not going to write a full tutorial so if it sounds interesting I suggest you do more research. The email hosting is typically focused at businesses as they are most likely to be wanting to host email on a custom domain.

Yeah, I think this is likely what happened, will be interesting to see what the investigation finds. I’m surprised there isn’t any sort of backup power for the voice recorder, it’s there to help investigate incidents, those 4 minutes would have contained a lot of vital insight into what was going on.

Runways can be used from either direction, usually they try to land with a headwind if there is significant wind I think. I think the localizer antenna can be at both ends of the runway if both directions have ILS approaches, but I’m not an expert. The concrete mound for the antenna is getting a lot of focus because it made a runway excursion so much worse.

It seems to me like they may have decided to make the landing then due to losing altitude and thinking they wouldn’t be able to climb again, but hopefully the investigation can figure out what probably happened.
