Helitack refers to "helicopter-delivered fire resources", and is the system of managing and using helicopters and their crews to perform aerial firefighting and other firefighting duties, primarily initial attack on wildfires. Helitack crews are used to attack a wildfire and gain early control of it, especially when inaccessibility would make it difficult or impossible for ground crews to respond in the same amount of time.
The term helitack first appeared in a 1956 Los Angeles Times article, which described the "first of a series of tests—tabbed the Helitack Program—on the use of helicopters in firefighting will start next week in the San Bernardino National Forest". The word itself is a portmanteau of "helicopter" and "attack".
The incident Helibase is the location from which incident helicopter support missions are flown, and where the helicopters assigned to that base are parked, serviced, and refueled. Usually a helibase is in a field location that is close enough to the Incident Base Camp so that supplies and personnel can be ferried by ground to the helibase from the camp in a timely manner. More remote helibases (i.e., nearer the fire) can be established to maximize efficiency and reduce flight costs. Occasionally, helibases are located at a nearby airport or backcountry airstrip. The name of the base is designated by the name of the incident, though on large fires there can be multiple helibases. Helibases are staffed with a Helibase Manager, Deck Coordinator, Landing and Takeoff Coordinator, Radio Operator, and numerous subsidiary positions operating in a Helibase Operations trailer or out on the landing pads. Crash rescue capability is usually assigned to the larger helibases. An "H" in a circle designates a helibase on an incident map.
We are the damned - the strain and moil
That death had washed from earthly toil
Drawn down by tides of hell, we boil
Like toads within a torrid slime.
Our sins were great - a deadly charge
And yet less heavy than our fate
We pour through hell's alembic large
Each soul transformed to vital hate
The good that in our hearts remained
By sin untainted, now is one
With vileness cankeringly ingrained
By earth and hell we stand undone.
For that which earth unfinished left
The consummation of the pit
From out the insuperable cleft
To where its lords presiding sit.
And watch with contestless sight
We burn, by double test refined
To clearest evil - purged quite
Of good or mercy from the mind.
Our souls are linked to vast despair
As to some nadir-founded rock
Where never hope descends to mock
Beyond the dip of terrene air.
We heighten to a hate that beats
In rage all impotently strong
Against the worlds that league with wrong
Whose pain each other's pain completes.
Would our gate were hands to draw
The lords of earth and hell beneath!
Would our hate were venomed teeth
To rend them through their mail of law!
Would that we might cleave with hate
The roof and base, and walls of hell
Wrench at its pillars till they fell
With ruin indiscriminate!
Immovable it stands, with springs
Of fire to tear its inward glooms
Where from, ascending high, our fumes
Are breath of incense to its kings.
