Next time we meet ask me and i will tell you some helecopter stories. It was my regular method of transport for a few years, but not for conversation here.
Taxi helecopters, very much so on air fields, on purple star we saw squadrons of cobra and sea Knight, taxi one behind another before taking off at camp lejeune
Airheads, not so much, such like locations tend to be drop in, straight out, but then there is no room or time for a taxi and the airspace is less restrictive.
Unfortunately accidents happen, I have been unfortunate to be in the area of two mid air helicopter collisions but thankfully not witness to either.
