Is anyone interested in recommendations for leveraging Microsoft Entra in OT? I have a few clients going down (or already down) this path. BTW, Microsoft released a new QR code authentication for Entra last February, which is an excellent fit for operators! @SANSICS #ICS410

This fall, I decided the only way I would get it done was to take the month of January off work and focus on it full-time until I finished my license. So, on January 3, I flew a CFI to our house to fly our helicopter with them to their training center five hours to the north.

I am proud to say I will fly our R44 home by myself tomorrow after completing my check rate today. It took ten days longer than planned due to bad weather and struggles finding an FAA DPE with availability to do the check ride, but it DONE, and it feels so good!

In the summer of 2021, I was able to get halfway through my private helicopter license before the pandemic inconveniently ended, and I had to go back to work. I tried squeezing training flights into my schedule but was not getting enough consistency to make progress…
