What an awesome day it turned out to be. We launched from Camp Ripley, MN and touched down right outside of Freedham, MN. The conditions could not have been better. We waited along time to get a picture perfect day and it was worth it. Enjoy the picutres and the video from the flight. We had a lot of fun with this group this year. Great kids and great families. Thanks for ALWAYS supporting the High Altitude Balloon kids!!

Here were the predicted paths of the flight using two models.

Here is the actual flight path recorded by flight data from tracker W0NY-3.

APRS.fi recorded data of actual flight path. Used a Big Red Bee primary tracker.

We had a group of kids design a timed dropping servo that was on a timer. They ended up dropping a glider plane they built out of styrofoam. The timer was programmed to drop the glider 45 minutes into the flight. Eli Karlgaard and his father Matt, designed and built the 900Mhz tracker that was attached to the glider. What an awesome project for a father and his son! Quality time that will never be forgotten. As of this post, we have yet to find the glider.

A successful touchdown! Had a student with a drone. He was able to locate the payload! The group walking through knee deep snow to get our stuff
That was a hard walk. Lots of snow on the ground. Heading back after recovery! Nice group photo. Great families and awesome kids!!

One group of students designed a glider to be dropped from the payload when the timer expired. Matt and Eli Karlgaard designed a tracker system for the glider the kids made in class. The glider was attached to a timed dropping system. Once the timer expired, it triggered a servo motor which let the glider drop. The timer was set to run for 45 minutes. Matt and Eli spent the better part of the day searching for the glider while the rest of the group searched for the payloads. You can see some of the data here that the glider sent back.

The last known location for the glider. This spring we can go and look for it.

Some other cool graphs showing some of the compiled data.

Great group shot with the kids. What a great group we had this year!!! Nice job young engineers!!

Now for the good stuff. Here are a bunch of pictures and videos from the flight. We flew four GoPros and one DJI Osmo camera. The Osmo got turned on but the record button did get pushed. One of the GoPros would not turn on so we only ended having three GoPros shoot video.

Great shot of Mille Lacs Lake from around 75,000 feet. We had slight cloud cover which is a neat effect.
Some of our students wanted to see what an egg does in space and if water would boil off a sponge at altitude.

Some good videos from that flight that we thought you might enjoy from a previous flight. We just like this video!

We flew a GoPro Session camera looking out. It got some great video. It is sped up times 4. Some great video of the country side as it makes it's way up to 111,003 feet.
