In PNG a number of years ago we were using 400' longlines on logging operations as the downwash was breaking off branches creating a hazard to the ground crews. You don't realise how high 400' is until you have a load on the end of a long line.

Years ago I needed 200' to set some logging rigging into a stand of Douglas Fir, the guy who was hooking me up used two 200' lines instead of just one. By the time I realized what he did I just went with it, I would not recommend it

mmmm, our hoists are 300 feet, it would be once in a blue moon we’d ever use anything like that, another 200 feet on top of that? I doubt you can see much

In September 75 we did a trial at Bishops Court, Northern Ireland using a 500ft strop from the Wessex 2 to position the detonating mechanism beside suspect car bombs. Having released the kit(weighing about 100lbs) we retired and let Felix remotely set a controlled explosion. Theory behind this exercise was that staking out a suspect car and neutralising it (especially down near the border) was man intensive, lengthy and risky so some bright spark at Lisburn said why not send a helicopter on its own to do Felixs job (they could be viewing the job from a safe distance). After 2 hours of being conned by the crewman and managing to correctly position the load a few times - the first attempt was by the drivers door but they wanted it moved to the boot! - it was decided that it was an impractical solution and trial abandoned. If Felix could see me and the target then so could the IRA, and a hovering helicopter would be a snipers delight. Deciding clincher was when I asked if the car was to be blown up whilst we were above it, how high would a Cortinas engine block fly and the cheerful Major replied how about a few hundred feet and I answered that there wasn't enough room in the cockpit for the two of us.
