Turbine Class

By Jacob -

This past week was spent learning about turbine engines. In the past, the majority of mission aviation aircraft had piston engines. However, this has changed over the years as avgas, which fuels these engines, has become uncommon and expensive.

Dan is conducting a borescope inspection of the Power Turbine blades. A borescope is essentially what the CIA uses for spy operations which means we are pretty cool! Well not exactly, but it is cool to take a camera on a long wire to inspect the guts of an engine.



I love this picture. It is a wordless expression of the eagerness to work together in fulfilling God's calling.

The compressor turbine and blades alone costs up to $160,000 new. Proper training and careful maintenance is essential. 




During this past week I was amazed by the seemingly endless knowledge our instructor, Ron Hollis. He has been working on PT6 Turbine engines for longer than I have been alive and it was a privilege to  learn under him. Covington Aircraft has been generously loaning him to JAARS a few times a year for the past 5 years.

Manna from Heaven

By Jacob -

Have you ever wondered what manna tasted like during the days of Moses? Well, wonder no more. I have solved the mystery! And with a few potatoes and minimal knifing skills you can replicate this ancient delicacy. First you need to chop them up Get rid of the bad spots (for looks so the wife will eat them) Oh, this potato chopper can be useful. All you need to do to get one is marry off your sister so that you can have a brother in law who appreciates fries as much as you do. Rinse and dry them I recommend putting the audience to work drying them But you know, the secret isn't in the potato, its in the oil. Deep frying food can make anything taste good ;) Sometimes I wonder if Prometheus was not bound for revealing fire to man, but instead for introducing the means to boil oil and thus make heavenly deep fried foods - something like giving up grandma's secret recipe or something...but it was Zeus's. But alas, I digress. Oh yah, and i

Navigating the Shortcuts

Getting to work has been an adventure of its own. Sometimes I drive, but lately I have been walking or riding my bicycle. It is a great  way to go over all the Swahili greetings (there are many) and get some fresh air (or be thoroughly dusted by a large passing vehicle). Many people walk great distances as few own cars and the public transportation does not go everywhere.  Below I have taken a video of my bicycle ride to work. I hope you enjoy! Some Blog Changes: I have aimed at keeping up a weekly blog but it is difficult to find the time to continue this aspiration. As such, we will be changing to a bi-weekly schedule.  Please let us know if there is anything you are curious about and would like to see a post on! We appreciate your feedback. We want to keep you involved in what we do even though we are half way across the world!

Parents Moving to Tanzania in 10 Days!

A few weeks ago we found out that the Christian school which Silas and Jason are attending was in need of a principle. Carmen's parents are both teachers and having cross culture experience we mentioned in passing that they should come... We could never have imagined, but they will be coming to Arusha in 10 days! They will be staying in a house that is less than a ten minute walk down the road. At first, this sounded too good to be true, but it is quickly becoming a reality. We will actually have family in Tanzania! This has been a very big step of faith for them and we would encourage you to help them out if you can. Below is their letter with more information.  Dear Family and Friends,   Recently our work at ProCare Physical Therapy came to an end. With this closing of a chapter in our lives God has opened the door to an exciting new opportunity to serve Him in Tanzania! Moving to Africa in Ten Days! After much prayer and consideration, we have accepted a
