while we wait for the next level of innovation in reliability
If a ballistic recovery systems is that, let's talk... But, can the combination be met, where the flying machine can also carry that weight, and remain a stable platform for it's deployment through the altitude range proposed? If the flying machine is in the altitude range of 100 to 200 feet, and falling powerless, will a 'chute deploy effectively and quickly enough to assure safety?
I expect that this type of flying machine has about the same reserve of safety as a "jet pack", and those seem to have flown out of ground effect. But the starry eyed wannabe flier needs to understand the reality of falling to earth, and the risks. Some things lack design redundancy...
