Two water tanks, each holding 3,655 litres (810USgal) of water, are located roughly at the aircraft's centre of gravity. The tanks are located predominately below the floor in the hull, with each side having a header tank that rises into the fuselage compartment. Forward of each water header tank is a 340.5 litre (681 litre total) foam tank, enough foam for 20 drops. Typically, the foam tanks are filled with a short-term retardant that "gels" the water, allowing it to hang up in the forest canopy and delaying run-off when it reaches the ground. https://www.flightglobal.com/flight-test-bombardier-415-the-superscooper/88562.article

Those look like eucalyptus not pine trees....but the same process applies.
The heat will not only desiccate leaves/needles, but it will also vaporize the oils in the leaves (needles in pine trees) making even the air in the canopy flammable. Eucalyptus trees are loaded with oils, maybe even more than pine trees. This is also called crowning, a crown fire, or a canopy fire. Once a fire crowns, it's nearly impossible to fight from the ground....or at all if the tree tops are close together.

Scary stuff. Where I live, in the Northern California redwood forests, that canopy can be hundreds of feet high and continuous in places.

Wait; wasn't that one of the loudest aircraft ever made too? As in--the military version could be traced by SOSUS sensors and NATO fighter aircraft directed to intercepts could hear the engines drumming through their canopies? (as mentioned at 7:43)

I mean; what was the noise level INSIDE the aircraft?

Anything is worth stealing, if you're a thief.

Work site and worker theft is very common. A friend of mine had over $1k of tools/gear ripped out of his secured canopied pickup while parked at home. Lock boxes etc only go so far if they can be ripped/cut out of your rig. Casing a site or following workers home is very real.

Think twice before you purchase that sweet deal on tools at the pawn shop.

I know right?

At first I was wondering why he was raising the canopy and planes were coming, then he said he signaled and they put up the flags... by that point I'd have to think the pilots aren't watching the flags, they are watching the guys on their wings and the runway... though obviously not enough attention to the runway... probably not much the guy who crashed into him could have done at that point as he didn't appear to have enough speed to take off and slamming to the side would have taken out the planes on his wings.

So it raises the question, why not use a radio to signal abort the take offs, and not just rely on a flag that might be missed.

At least he gave the guy who crashed into him a hug rather than a knockout for clipping him.

A lot of the clips of Spitfires in this are actually Hurricanes (the Spitfire is the one with the bubble canopy). Of course, they had the same engine in them with the same problem.

Great film, though, Battle of Britain. I understand a lot of the effects in it were inspirations for Star Wars (particularly the head on shot of a pilot in his cockpit which is starting to explode around him and then cut to the external shot of the model exploding).

ed: You don't actually see a Spitfire until 0:26 and the plane used as an example doing a roll is a Hurricane.

The canopy is easier to see through than the fuselage, so that would be safer... although i think it has more to do with the control surfaces work better pulling up than pushing forward.

FEAR.

It is amazing to me how undeniable in every-way if you systematically take apart his masterpiece of nothing and throw it into tiered columns and subject matters via science and psychology, setup a little like a tree you will always find that the source component of everything you've just heard is FEAR. It is the literal trunk of the tree with the neurons and chemical impulses that make us being the roots. Everything above the trunk in the canopy is DRIVEN by that fear meaning that if it happens to be a large amount of information then you MAY NEED TO discredit it.

Everything this man has ever said may be a result of fear, we don't know for sure, but in this situation EVERYTHING was. But, if you look at his other shows or speeches I bet he has a lot of anger driven (anger is fear, BTW) pieces, but they probably all come from one source and that is FEAR.

This is why so many religion speakers and believers fail. They don't understand themselves. They don't do enough self-introspection except to get past the front door. If you kept looking you TOO would also realize the same things scientists say, these things all stem from one primary system in our body: the fight or flight basically. For many of us WE ARE fighting, but oh so many are just running--trampling and killing anything in their path in irrational escape to nowhere, nowhere.

All this thread needs is a 'In Soviet Russia...", and we have a full list of outdated internet cliches.

Meanwhile, no one says 'canopy' like Our David.

Can't believe he didn't have a couple people on ropes, sure, you can make the right cuts so that the tree *should* fall in a certain direction, but the weight of the canopy is extremely difficult to gauge, as well as any unexpected winds...

The relatives cut down a twinned giant poplar hanging over their house last year, and I was on ropes, the tree definitely hovered after it was cut through, luckily we tied on high enough and had enough leverage to counter it from falling on the house even with the proper directional felling cuts made. My uncle was EXTREMELY happy he asked us to pull...

Goose is amazing at everything he applies himself to... Programming. Surgery. Faceplanting F14 cockpit canopies.

Actually, costs for an 800 pound plane are $3,800 to $4,000 dollars based on the quotes from BRS Aviation here http://www.brsparachutes.com/full_price_list.aspx
I would not call that "much more" than a few thousand dollars. I realize there may be some additional installation costs, but still, we're talking far less than 10 thousand dollars.

Cost for such system ( Ballistic rescue parachutes ) are much more than just a few thousand dollars. When you get the FAA involved costs for a single bolt will skyrocket. In order to manufacture such a system for aircraft you must secure an STC from the FAA (http://www.faa.gov/aircraft/air_cert/design_approvals/stc/), this alone can cost the investor hundreds of thousands of dollars. Which he would have to pass along to the consumer. Each individual aircraft would need an STC as well if the system was not designed for that exact airframe. Cirrus aircraft all come with the CAPS system. http://cirrusaircraft.com/parachute/



unfortunately thats only the tip of the iceberg. For a normal light aircraft cessna 172 style its more like $20000, plus fitting costs, plus paperwork and certification costs.
