Helicopters in Combat-Vietnam
We introduced this topic in the current PHI EMS crash thread and rather than divert a very important discussion about EMS safety perhaps we might take the opportunity to explore helicopter aviation during the Vietnam War in which a lot of us old geezers took part in.
This is a link that shows helicopters operating into a "Hot" LZ where the infantry are engaged with the NVA. It is one of the better video's I have found so far.
