Is red fire retardant toxic?
The fire retardant is generally safe — the Forest Service has said its risk of chemical toxicity is minor for most animals, and it predicted no risk for people who are accidentally splashed — but the sheer volume that comes out of a plane is very heavy. The fire retardant is gooey — sticky, even, Turner said.
Is fire retardant bad for the environment?
The long-term fire retardants are ammonia-based chemicals considered to be non-toxic to terrestrial organisms and of low to moderate toxicity to aquatic organisms (Finger 1997).
How much fire retardant can a DC 10 carry?
The turbofan-powered aircraft carry up to 12,000 US gallons (45,000 Liters) of water or fire retardant in an exterior belly-mounted tank, the contents of which can be released in eight seconds.

As a result the federal government will pay for about 75% of the costs to fight that fire and the state will cover the rest.

Why did Lockheed TriStar fail?
The L-1011 TriStar’s sales were hampered by two years of delays due to developmental and financial problems at Rolls-Royce, the sole manufacturer of the aircraft’s engines. After L-1011 production ended, Lockheed withdrew from the commercial aircraft business due to its below-target sales.
Are any Lockheed L-1011 still flying?
Q: Do any airlines still use the L1011? A: No, none are still flying for commercial airlines. The L1011 was technologically advanced when it debuted in 1972, but more modern and efficient airplanes have replaced it in airline fleets.
Why do Aeroplanes fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
