15th and 16th come to an end, May 5th 2022

We launched AA6DY/4 and KK9H/2 last night at 7pm from Willow Hill Golf Course just North of Chicago Illinois, what a nice place. We never got a reading from AA6DY/4 though the launch looked beautiful.

We got our first reading this morning at 5:58 a.m. Central Daylight Time, 10:58 zulu. KK9H/2 woke up over Ft. Wayne Indiana, well that’s what the map says. I believe it actually woke up near Hershey, Pennsylvania and lost contact East of Ocean City Maryland at 10:18 a.m. 15:08 zulu. Flight 10 hours asleep and 5 hours awake. Total flight time 15 hours and 8 minutes. I’ll send this back to our Technical Team if it’s possible to go from Ft. Wayne Indiana to Hershey Pennsylvania in 2 minutes. First reading was at EN71mb at 10:58 zulu and FN10sg at 11:00 zulu.

Our Technical team had our max altitude at 26,000 feet and steadily losing altitude while awake. Guessing our Max Altitude during the first 10 hours of flight, that’s a tough one and another reason to launch early.

After losing several balloons in the trees leading up to yesterday’s launch, we were looking for anytime, day or evening where the weather would be favorable for a launch. Our best opportunity was 7 p.m. last night. Well, now that we got that evening launch out of our system, we’re going to try again for a morning launch, more data early on.

Looking at our arsenal of somewhere close to 100 balloons,; 36″ Chinese Round pancake, SAG, Yokohama and another 30″ Chinese made Sphere. We’ve had some nice flights with the 36″ Round, albeit, not at the desired altitude. We’re back to the testing phase. I’d like to launch one of each balloon at the same time, I’ll see if I can convince the group.

15th and 16th Launch KK9H/2 and AA6DY/4, May 4, 2022

We had 2 beautiful launches today at our brand new location high on a hill at Willow Hill Golf Course in Northbrook, Illinois. A big thank you to Kari and Kent for letting us use this great location, please visit their website and view their gallery https://www.willowhillgolfcourse.com/

Michael, AA6DY and I met at his home to prepare the balloons. We had just received our shipment of 10 SAG balloons from balloons online. Because we ordered 10, shipping was included. For $166.00 we have the same balloons that Tom Medlin W5KUB was very successful. While I’m writing this, Tom’s balloon W5KUB-110 had flown for 34 days, 60,000 miles and almost 3 laps around the world crashing just west of South Korea in the Sea of Japan. Congratulations to Tom on a wonderful flight. Didn’t take long to get another one up, Tom is now flying W5KUB-111. For more information on Tom’s flights please visit https://ham-tv.com/balloon/

I have written before, that we are part of a larger Pico Balloon community and share information freely. We had nearly flown around the globe on 2 flights using the 36″ round pillow shaped balloon. But to get the altitude and be as successful as Tom and many others, we needed the 32″ Sphere shaped balloon. Currently out of stock https://balloons.online/orbs-32-silver/

I should mention, that we had successful lift off for our two balloons KK9H/2 and AA6DY/4, but will have to wait till tomorrow to get the tracking information We weren’t able to get a signal from the twilight of the 7p.m. launch. As I started to say above that Michael and I met to prepare the balloons. There has been a lot of discussion on how to seal these special balloons. We decided to cut up one of these balloons and test the sealing. The body of the balloon sealed well, and the valve itself sealed well. We first inflated the balloon to test the self sealing and under pressure there was no leaking, but to heat seal we had to remove the paint inside the valve with acetone and a Q-tip. We sacrificed a balloon to test the sealing, pictured below.

The balloons that we chose for this launch were sold by balloons online and manufactured by SAG. Unique to this balloon is a valve and a separate tab that we use to tie the package. The Sphere balloon is very close to being round like a ball so having the package holder away from the valve works well. pictured below

Next was filling the balloons to 24.2 grams including 6 grams of free lift

Next Launch May 4th 2022, Willow Hill Golf Course and Park, Northbrook Illinois

Looking back at our previous launches with our first launch on September 25th 2021, which I refer to as our first learning experience. I used to call a flight successful if the balloon left the field, this was after all a big learning curve for everyone involved. It wasn’t until our 8th Launch, December 22nd 2021 that we were able to find a balloon that stayed up for more than a day. It was also our opportunity to switch from Helium to Hydrogen. So, new balloon and Hydrogen gas, equals 19 days and 10 days of flight time. This was our first awakening of the possibilities of world travel.

Though we conquered one issue, staying afloat for multiple days, we suffered from another issue, not being able to go above 28,000 feet. In our subsequent flights we were hoping to achieve the magic altitude of 40,000 feet. What 40,000 feet gets us is flight above the clouds, above the weather. The two ways to achieve that goal is a smaller package, bigger balloon or a combination of both.

The biggest obstacle we’ve had as of late is the weather for launch and the launch site. The location for our longest flight we actually hit 2 objects on different days. First there was a tree and luckily a recovery of the tracker. Ten days later with the same tracker we hit the backstop of a baseball diamond, recovery of the tracker and two hours after that, a new balloon, two more grams of free lift gave us a 19 day flight. Over the next two months and starting to name the trees, we moved to another location with a successful launch of a two balloon package, and flight from Highland Park, Illinois to the Alaska/Canada border in 10 days of flight reaching 28,000 feet.

Our long haul flights were achieved using the 36″ round pillow or pancake shaped balloon costing around $2 each from the Party World Store. This balloon was the same shape as our original Qualatex party balloon but had a better quality for longevity. One balloon got us to 24,000 feet, two balloons to 28,000 feet.

After following the successes of Tom Medlin, W5KUB who started using a 32″ Sphere Yokohama balloon. These balloons though smaller in diameter are completely round making for a higher volume to achieve the desired altitude of around 40,000 feet. You can follow Tom’s flight here https://ham-tv.com/balloon/

So now with our arsenal of balloons, 36″ clear Chinese, 32″ Yokohama Sphere and other 32″ Sphere’s we were ready to launch, though having one other small problem.

When we started naming the trees at our last location, we were on a treasure hunt for our ideal location, high above the trees. Willow Hill Golf Course was suggested by several members of our group, though it wasn’t until I went searching for our last tracker after the rain had subsided a bit, that I decided to head over to Willow Hill. It was a cold rainy day and a short drive from our last site. Willow Hill Golf Course sits 200 feet above street level with beautiful views of Chicago’s Skyline, miles away.

There I met Kari Knebelkamp who with her husband Kent own Willow Hill Golf Course and Park. I shared with Kari our Pico Balloon project and asked if we could launch at their site. Kari was very excited about our project the science of Pico Ballooning, and our work with youth.

For those wanting to come by and cheer us on we’re looking at our next launch tomorrow May 4th 2022 at Willow Hill Golf Course and Park, 1350 Willow Rd Northbrook, IL 60062. Michael and I will be preparing the balloon and look for us meeting close to 6:30 p.m. Bring a camera, it’s a beautiful view.

I’ll post tomorrow with the launch information and pictures.
