I have to be very careful here but I feel a warning might be in order. You can find prices for the Parazero Safeair parachute system from $199 up to over $1100. The difference being the paperwork that accompanies the complete package vs. just the unit itself. The paperwork is basically the waiver request for "flying over people". My initial request was addressed and the reply was a request for more information. The problem was the information was only available for "the price". If you are a small independent outfit/company it is difficult to justify spending this amount of money for paperwork proving the parachute system on your Phantom will work as advertised. **shouldn't that be included with all Safeair units sold? Bottom line, I included references to FAA studies and all the standards established by the industry and even more detail regarding how the operation would be conducted, in my response, only to submit and receive a denial less than 24 hours later. I don't necessarily expect much in the way of reaction to my rant, but if a similar situation has happened to you, you might want to share.
