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.

500 ft Jesus I would need some binoculars on my helmet to see the remote hook ! Much respect !!

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 :ooh:

Here is an example. New poles brought in. Aircraft is B205, LongLine 100FT and poles are 85FT tall. The powerline is LIVE

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.
