We're In Full Swing Now
After a long wet, cool spring, we are in full swing now with March Browns, BWO's, and sulphurs hatching. We even saw a Slate Drake this week, but he's a bit early. Guiding and fishing has been good and Fishing Creek is beautiful.
I had the opportunity to work with Kylie and Kelsie Freiman this week. Although I don't get many kids in my classes, these girls were the exception in more ways than one. They were interested in the turtles, minnows, and dragonflies around the pond and had a blast catching bluegills and strippers. Here they are with another client who came recently to fish.
Behind the Brand – Episode 3
We think you'll find this clip very interesting, we sure did. You might think it's a boring factory tour, but you'll be pleasantly surprised.
Cathy's favorite travel blog, The Travel Insider, has an interesting perspective on laptops on planes. Hope you enjoy:
Laptops – Will They Need to be Checked or Not?
More confusion and ambiguity this week about what might be in store for us and our laptops when flying in the future.
The Europeans are saying that the Americans have agreed not to impose any bans. But the Americans are denying that, and are talking about maybe banning laptops not just on flight from Europe to the US, but on all flights, to and from, all international destinations. This article exposes the contradictory stories that are circulating.
If that were to happen, then it becomes almost certain and indeed necessary that a similar ban apply on domestic flights, too. If a person can smuggle a bomb onto an international flight inside a laptop, one has to believe they could do the same on a domestic flight, too.
There was also a timely incident this last week that showed the complexity of the issue. A JetBlue flight from JFK to SFO had to make an emergency landing in Grand Rapids after a laptop battery is said to have ‘exploded’ and burst into flames.
The laptop was with the passenger, in the passenger compartment of the plane, and flight attendants were able to safely extinguish the fire. But what would have happened if the explosion/fire had happened with the laptop inside the passenger’s suitcase, in the luggage compartment?
Until there is some way to safely contain laptops and their batteries in the cargo holds of planes, we risk changing from one sort of bomb (a terrorist device) to another sort of bomb (an exploding battery). Are we really any the better off in such a case? Not really, because we still might have the terrorist type bombs in the cargo hold, plus now the battery type bombs too.
Which Are More Dangerous – Batteries or Explosives
We all know that explosives are dangerous. We’ve seen the movies, with amazing explosions. On the other hand, generally we all perceive batteries as safe, and ‘the worst that can happen’ is a bit of a fire.
But that ‘bit of a fire’ should not be under estimated. Modern laptop batteries these days contain an astonishing amount of energy, which is why, if they ‘misbehave’, their fires are very hard to extinguish. Their ‘fire’ is actually a slow-motion explosion – lots of heat, but not any appreciable shock wave.
A half stick of dynamite (1.25″ in diameter and 4″ long) has about 500,000 Joules of energy within it. A 100 Watt hour laptop battery has about 360,000 Joules of energy within it. Batteries already contain almost as much energy as explosives, and as battery technologies improve, will continue to hold more and more energy.
None of us could walk on a plane with a half stick of dynamite. But my Dell laptop has a 97 Watt hour battery – and that’s about as powerful as 3/8 of a stick of dynamite. Maybe terrorists don’t need to smuggle explosives into laptops – they just need to know how to trigger ‘runaway thermal events’ in the batteries already in the laptops
