Sorry to interrupt this thread but this is important. A National call to action from CASAA regarding bringing e-cigs on planes is being brought forward from Senator Blumenthal of Connecticut. He wants to ban them from your carry on and checked luggage and is trying to slip it in a bill as an amendment. Contact your Senators ASAP! Here is the CASAA link.

CASAA: National Call to Action - Take action to oppose a ban on flying with vapor products!

Several Airlines have already put a ban on lithium batteries being on-board ( American Airlines has a total ban)... but there are exceptions, low voltage, low CDR and minimal size are the acceptable factors ( aka button types) if they do vent, the amount of venting will be minor enuf not to cause immenent threat of fire... airlines are also looking into laptop, Ipad, large Iphones, and along with all ICR type cells being on the no fly list... altho, thought has been given to the idea of flame proof shipping containers... ( basically hi pressure metal boxes that vent very slowly thru a flame capturing "muffler")

and here is the clincher... the "Blackbox" on the airlines... powered by lithium batteries... and a rather large array at that.

I'm still here on ECF... sort of. ;)

That's it. Let's definitely write Dicky and tell him that no Blackboxes should be allowed on planes... :facepalm:


Hi, What is This'ers! I've missed you, and I collect ducks. Uh huh.

Where are we? Whose turn is it? And please forgive my lack of hostessness.

A black box is a pretty special container. They are designed and tested to withstand > 3 thousand G, 2000 degrees temp, deep submersion and a bunch of other very extreme conditions. All with complete data recovery.

Ahh found this ...

  • Crash impact - Researchers shoot the CSMU down an air cannon to create an impact of 3,400 Gs (1 G is the force of Earth's gravity, which determines how much something weighs). At 3,400 Gs, the CSMU hits an aluminum honeycomb target at a force equal to 3,400 times its weight. This impact force is equal to or in excess of what a recorder might experience in an actual crash.
  • Pin drop - To test the unit's penetration resistance, researchers drop a 500-pound (227-kilogram) weight with a 0.25-inch (0.64-centimeter) steel pin protruding from the bottom onto the CSMU from a height of 10 feet (3 meters). This pin, with 500 pounds behind it, impacts the CSMU cylinder's most vulnerable axis.
  • Static crush - For five minutes, researchers apply 5,000 pounds per square-inch (psi) of crush force to each of the unit's six major axis points.
  • Fire test - Researchers place the unit into a propane-source fireball, cooking it using three burners. The unit sits inside the fire at 2,000 degrees Fahrenheit (1,100 Celsius) for one hour. The FAA requires that all solid-state recorders be able to survive at least one hour at this temperature.
  • Deep-sea submersion - The CSMU is placed into a pressurized tank of salt water for 24 hours.
  • Salt-water submersion - The CSMU must survive in a salt water tank for 30 days.
  • Fluid immersion - Various CSMU components are placed into a variety of aviation fluids, including jet fuel, lubricants and fire-extinguisher chemicals.

Here's another hint.
