On leave and saw this....big.
When I was in college, I was a lineman at the local airport. We had HTSI as a tenant at the field, and they had probably a half dozen or so skycranes (as well as a couple CH-53's and super hueys.....the stretch version the Shah of Iran had ordered). I remember one socked in early Oct evening when they all had their flyoff from fire season. Sounded like the earth was about to explode as they all sequentially came down the chute and appeared over the runway. Real cool helos.
