Max underslung load for helicopter(s)?
A friend put a question to me which I can't resolve from my books or a web search. What is the heaviest thing which can be lifted by helicopter? Multiple helicopters allowed (eg. two Chinooks).
There is a practical reason for this which I can't go into yet, but suffice to say I think we ought to restrict it to "western" helicopters and rule out the Mi-26 - hence the Chinook example.
