Here are some lessons that we learned the hard way with our High-Altitude Ballooning program.
1. Do NOT turn the chase van off while preparing for a launch.
If you are using the vehicle to power your antenna and computer and/or other miscellaneous devices, it will drain the battery and you will have to get a jump start before starting the chase.
2. Do NOT forget your APRS antenna at home.
You will be dead in the water and have to run and get it which will delay the launch.
3. Do NOT forget to turn on all of your cameras and probes before you launch.
If you turn on the cameras too early, the batteries may run down and they will stop taking photos before you reach maximum altitude. The best way to prevent this is to have a flight list and follow it. Turn on everything inside the pods before you wrap them up and turn on the external cameras right before you fill the balloon, because once it leaves your fingers, there is nothing else you can do.
4. Do NOT count on your cell phone working during the chase.
If you are on the interstate or near a large city, there would not be much of a problem. However, if you go just a few miles out into the country, cell service will be spotty at best. Even with a booster, you are going to run into problems if you rely solely on your cell phone service for some vital tasks.
5. A car GPS won’t cut it.
We originally used the removable GPS from our car to try to find the payloads. Even though it could get us to within 20-30 feet of the correct latitude and longitude, we could still not find the payloads in very tall corn. When we had a good hand-held GPS like the kind used for hiking or geocaching, we were able to walk right to it.
6. Have a plan for feeding the chase team.
If you let a bus full of students stop at a convenience store or fast food place during the chase, you will probably miss the landing. Even if you have packed sack lunches, drinks, and snacks, you will probably need to stop for a bathroom break which will take a while if you have lots of people. If you have a small advance chase team, they could go ahead of the larger group and have a greater chance of seeing it land, making it much easier to find.
7. Have a plan when you get to the touchdown site.
Make the participants take the time to put the coordinates in their hand-held GPS units, have them go in teams, and make sure that one person in the team has a walkie-talkie set to the correct channel. We have had students run off willy-nilly when they hear approximately where the payloads landed so they can be the first ones to find it. Most of them are not used to walking long distances in the heat of summer through corn or down dirt roads. They get disoriented easily and might get hurt walking on uneven ground. If everyone has a walkie-talkie, they will hear when a team finds the payloads and everyone can regroup and if there is a problem, they can get help quickly.
