of the airports in the uk are closed. correct. this is not precautionprecautio. this is a mandatory do-not-fly zone literally, because this is a particle blonwn up many thousands of times. you don t want that going through your car s engine, let alone a jet engine, and this because it s ash melts back down into lava and then like glass, like you said earlier, like ob siddian, and then it deposits itself on the back of the jet and the jet engine on the plane can choke itself. yep. look what happens here. you hit the particles, i know they re small, but you hit them with the plane, it scours the plane, you can t even see out of the windows at all and it can also just scour all the paint off and actually put dents in it if it hits it hard enough. so, you can there are literally there are mandatory reasons why you don t fly in volcanic ash. right. and this is the time. we ll stay on that. we ll be back with you in a minute. there have been instances where planes have had all
engine to a halt. one more picture. even more even though the pumice-like nature of this. the problem is when this gets into the internal combustion part of the jet, the melting part of that ash is lower than the temperature of the engine. literally the ash melts back into lava, it could shoot out the end of the jet. by the time it gets shot out of the the end of the jet, it cools down below the melting point of lava and so it just coagulates and just collects on the back of the jet and literally jets stall and the jet s engine stops running and planes fall out of the sky. every opportunity, every chance that this has happened so far, the pilots have been able to restart the engines eventually. but it is dangerous. you can t fly through it. we just lost it. that s okay. when it gets out there and it s just it s not a plume like that anymore, it s hard to tell whether it s a cloud or whether
