American Wings
Maj, We had some American riggers who were on a brief exchange to Australia and that's how the opportunity arose. A couple of things I remember of these jumps are that we had to complete three jumps using the American rigs and we had to jump from the C141 "Starlifter".
The Australian parachutes are a "T10B-D" whereas the American are a "T10B" (no D). This means they are exactly the some 'round' canopy with the only difference being the Australian ones have a small patch of lightly padded canvas under the chest strap and two groin straps. There is also a small canvas strip that runs across between the groin straps, forming a small 'seat'. These changes make the Australian parachutes 'Deluxe' - hence the D. They may not seem terribly significant but they do make everything a lot easier to get properly positioned in the first place. Once you have exited the aircraft, it is too late to tuck any of the block 'n tackle away if it is in the wrong place!
The other thing of significance is the ride in the C141. It is a huge aircraft. I seem to recall it is about the same size as the C130 Hercules, just about three times longer. Prior to one of the jumps at the Londonderry Drop Zone (Western Sydney and I hear no longer used for parachuting), we spent about 45-60 minutes Tactical (Tac Flying) around the Blue Mountains. Fantastic fun to be flying at what seemed to be ridiculously low heights around the mountains. No lunches were lost but it would have been interesting if it were at night!
For those not aware, most military jumps from the larger aircraft like the C130 are from the side parachute doors. We were trained to take a 'driving step' out from the side doors so we wouldn't "count rivets" down the side of the aircraft. The C141 side doors are equipped with wind deflectors that help reduce the impact of jumping into a 140kt windstream. The idea is that a small pocket of still air allows you to step into this space, drop away from the aircraft so you don't "count rivets". Of course some of my peers were over trained, couldn't help themselves and still managed a driving step out of the starlifter and into 140kts. They reported it as being the quickest left turn they ever did. :black_eye:
I did my training at the Parachute Training School, at HMAS Albatross. Many of the older riggers enjoyed sharing stories of their time at PTS Williamtown.
