The comments about the stability of the Bambi following a drop are, of course, quite correct. It may be worth noting that the lines we used back in the 90s were steel and very heavy, which influenced not only the flight characteristics but also the length of the line. 30ft (we weren't much into metrics) was about the limit of steel cable that could be handled by a pilot, especially when we started adding not just the household cable to run power to the solenoid but also a hose for the feed from the Sacksafoam! With the introduction of kevlar lines this restriction disappeared overnight and 100ft became the norm of what could be handled by one man.
