Now being an ex "Tanker Wanker" myself I found this youtube grab very interesting.
This footage highlights the inherent risks and dangers of air-to-air refuelling. I myself have personally witnessed occurrences very similar to one or two of the events highlighted in this footage, (once lost a hose between Amberley and Towoomba ......I am sure there would have been one very surprised Darling Downs farmer when he saw what was "growing" in one of his crop fields on that occasion )
Check out the very close call between an E-3 and it's KC-135 Tanker .......soiled flying suits all around on that occasion I reckon.
