There are additional screen captures of the setup and launch process "here":https://opendesignengine.net/dmsf/far-horizons-project?folder_id=47. The screen captures below show the name of the video they came from, and the time to seek to within the video. This will allow you to see more detail of how a step in the process is done. Refer to the [[Launch Videos]] page for a full list of the launch day videos.

Keep in mind that you may want to do some sections of the procedures in parallel. For instance, you may want to assemble the tubular payload platform and attach the payloads while other members of your team prepare the balloon itself.

h2. 1.0 Pre-Departure Operations
36 1 Jeremy Wright
37 4 Jeremy Wright
These are operations that are completed before the launch and chase teams leave for the launch site.
38 4 Jeremy Wright
39 5 Jeremy Wright
* *FHPOM 1.1* Break personnel up into teams based on experience and interests, but make sure to have a minimum amount of people on each setup task.
40 5 Jeremy Wright
* *FHPOM 1.2* Make sure that your balloons are not up against anything that might damage them in your equipment transport bag.
41 5 Jeremy Wright
* *FHPOM 1.3* Once you have ensured that all of the equipment is in the transport bag, secure it with zip ties or some other method to keep someone from removing items.
42 4 Jeremy Wright

h2. 2.0 Setup Operations
44 4 Jeremy Wright
45 6 Jeremy Wright
These operations cover assembling the flight vehicle and attaching the payload(s).
46 6 Jeremy Wright
47 8 Jeremy Wright
* *FHPOM 2.1* Weigh each component of the flight vehicle to ensure that it’s not over 12 lbs total, and that no single component weighs more than 6 lbs. Enter this information in the "PAYLOAD WEIGHTS" section of the "Flight Log Sheet":http://opendesignengine.net/dmsf_files/50?download=.
48 9 Jeremy Wright
49 7 Jeremy Wright
* *FHPOM 2.2* Calculate the amount of lift needed based on payload weight(s) and ascent rate.
50 7 Jeremy Wright
* *FHPOM 2.3* Set up a workspace by laying out the ground tarp and ensuring that it is clean and free of debris, oils, etc. “Clean is key”.
51 10 Jeremy Wright
52 7 Jeremy Wright
* *FHPOM 2.4* Lay the helium tanks on one side of the tarp to help keep it from blowing away.
53 12 Jeremy Wright
54 7 Jeremy Wright
* *FHPOM 2.5* Remove the safety cover from the helium tank(s).
55 7 Jeremy Wright
* *FHPOM 2.6* Attach the custom built fill connector’s regulator to the first helium tank.
56 11 Jeremy Wright
57 11 Jeremy Wright
58 7 Jeremy Wright
* *FHPOM 2.7* Use a crescent wrench to tighten (snug) the regulator’s connector to the tank’s valve.
59 7 Jeremy Wright
* *FHPOM 2.8* All personnel who help steady the balloon should wear cotton gloves to help protect the balloon.
60 7 Jeremy Wright
* *FHPOM 2.9* Keep the balloon from coming in contact with anything except cotton gloves during fill and launch.
61 7 Jeremy Wright
* *FHPOM 2.10* Open up the balloon bag and unroll the balloon away from you with the open neck closest to the helium tanks.
62 7 Jeremy Wright
* *FHPOM 2.11* Slip the 2” steel attachment ring onto the neck of the balloon.
63 13 Jeremy Wright
64 7 Jeremy Wright
* *FHPOM 2.12* Slide the neck of the balloon over the 1” outlet throat of the fill connector.
65 7 Jeremy Wright
* *FHPOM 2.13* Wrap the neck of the balloon and tape it securely to the fill connector, making sure to leave a folded tab at the end so that you can remove the tape later. You’re securing it against about 20 lbs of pull. Use one continuous wrap that goes down the neck, overlaps the fill connector body, and then goes back up the neck of the balloon.
66 14 Jeremy Wright
67 14 Jeremy Wright
68 7 Jeremy Wright
* *FHPOM 2.14* Open the main valve directly attached to the helium tank, and then open the secondary regulator.
69 7 Jeremy Wright
** *FHPOM 2.14.1* For a 1200 gram balloon and a K size tank, you’ll add approximately 1-1/2 tanks of helium to the balloon.
70 7 Jeremy Wright
* *FHPOM 2.15* When switching helium tanks, make sure to close the main valve on the tank first before closing the secondary regulator. Otherwise pressure could get trapped in the secondary regulator’s body that is then released forcefully when the connector is loosened with the crescent wrench.
71 7 Jeremy Wright
* *FHPOM 2.16* As the balloon inflates the fill connector’s paracord loop can be attached to a helium tank’s valve to hold it down.
72 7 Jeremy Wright
* *FHPOM 2.17* The paracord loop on the fill connector can be attached to the empty helium tank when switching to the second tank.
73 15 Jeremy Wright
74 15 Jeremy Wright
75 7 Jeremy Wright
* *FHPOM 2.18* When filling the balloon in an outdoor location, use a clean tulle “tarp” to cover the balloon and keep it stationary.
76 7 Jeremy Wright
* *FHPOM 2.19* During filling one person with leather gloves can hold the fill connector, wrapping the para cord around the wrist of their leather glove, and two people with cotton gloves should be on either side of the balloon to keep it from blowing around.
77 16 Jeremy Wright
78 7 Jeremy Wright
* *FHPOM 2.20* Use a luggage scale to measure the lift of the balloon. Make sure to take the weight of the fill connector into account when doing this. Adler puts a line on the hose leading up to the fill connector’s PVC main body, and they have measured the weight of that part of the connector. When measuring the lift, they pull the balloon down to where the line on the hose touches the ground as they’re measuring the lift.
79 17 Jeremy Wright
80 18 Jeremy Wright
* *FHPOM 2.21* Once the balloon is filled to the proper generate the proper amount of lift, double the neck over and duct tape it securely before removing the fill nozzle.
81 18 Jeremy Wright
** *FHPOM 2.21.1* Make sure that the steel ring is at the bottom of the neck's loop so that the rest of the launch vehicle can be attached.
82 18 Jeremy Wright
83 19 Jeremy Wright
* *FHPOM 2.22* Make sure to use 50 lb rate zip ties to secure the payload(s) to the train line or frame.
84 19 Jeremy Wright
* *FHPOM 2.23* Ensure that all your equipment with a contact number, what it is, etc.
85 19 Jeremy Wright
* *FHPOM 2.24* Attach the parachute to the tubular payload platform.
86 19 Jeremy Wright
87 19 Jeremy Wright
* *FHPOM 2.24* Attach the tubular payload platform to the steel ring on the looped neck of the balloon via the parachute using a 50 pound zip tie.

h2. 3.0 Launch Operations
91 1 Jeremy Wright
92 7 Jeremy Wright
* *FHPOM 3.1* When launching the balloon in an outdoor location, use a clean tulle “tarp” to cover the balloon and keep it stationary.
93 7 Jeremy Wright
* *FHPOM 3.2* After filling, and during transfer to the launch location, make sure that the balloon does not touch the ground due to wind or mishandling or it may burst.
94 7 Jeremy Wright
* *FHPOM 3.3* Ensure that the parachute and payload line(s) are not tangled or twisted prior to release.
95 21 Jeremy Wright
* *FHPOM 3.4* Move the flight vehicle to an open area, ensure that nobody is caught on the FV in any way or going to be injured by the release of the FV, and then release the balloon and the payload platform.

h2. 4.0 Chase and Recovery Operations
99 1 Jeremy Wright
100 7 Jeremy Wright
* *FHPOM 4.1* The chase vehicles will be decided by what’s available and how many people are participating in the chase and recovery operations.
101 1 Jeremy Wright
* *FHPOM 4.2* In certain rugged or isolated areas, 4 wheel drive chase vehicles may be required.
102 1 Jeremy Wright
* *FHPOM 4.3* At least one chase vehicle needs to have an APRS capable receiver setup suitable to track the balloon platform’s real-time location.
