Well, my first thought would be what could have happened (hypothetically speaking).
Did the rocket not descend to the main alt? 400 or 800 ft power lines? Tree? Radio tower? Mountain. Caught on an airplane or hot air balloon? But I gotta wonder why was the launched in violation of the safety code of hazards in the launch site?
Ok if the rocket reached main alt but did not fire the main? What is it hung up in (tree, powerline, radio tower) and why was it flown in violation of the safety code (hazard in launch site)?
Ok it's there but why didn't it fire? Battery dead? Power leads came loose? Ematch not connected? Bad ematch? Match fired but didn't set off power? Not likely to be an issue.
Ok, it's hung up and the alt is good, primed and ready to fire the charge when the wind blows right.
Who's getting it down? Lineman? He's going to take the time to look all over the rocket to find the little switch and has a small screwdriver handy? Or is he in a hurry to fetch this pain in his rear, yank it off the line and toss it in the bucket.
Cable guy might at least have the right sized screw driver.
When either of them grab the rocket to read that little warning and supposedly disarm the switch, did they just cover the vent hole?
Did you mention what they should do when you called them and paid the huge fine for causing them this pain in the rear?
If the chute wasn't stripped away, it would be a whole lot closer to the launch pad and not in a tree or powerline which wouldn't be in your launch field.
Does anyone have any real situations or do we discuss the possble danger of a static spark when pouring BP from a 1lb can into the ejection canister?
