I'm familiar with those two. They're also wrong. I don't care who you are or how many hours you have as a pilot. You have to understand that there is nothing, absolutely nothing that a conveyor can do to hold a plane stationary. All the conveyor can do is push against the bottom of the plane's wheels. That would make a difference in a car, because a car relies on its wheels to push itself forward, but with an airplane, the propeller pushes against the AIR and will move the plane forward regardless of how fast its wheels are spinning. I hope you do try it out yourself. Most of us understand physics well enough to not need to. |

quote: I am new to these forums but I just had to sign up to vent some of my frustrations. I was one of the first female commercial pilots in the U.S. I am amazed at all the pseudo intellectuals who are chiming in here and lecturing us about every aspect of aviation physics without ever having flown a plane. Since I am now retired I am thinking about trying to get permission to use this Fosbucraa conveyor belt to do some experiments with my small plane. It's 100k long and should be more than adequate for what I have in mind. You could hardly call what the mythbuster boys had a real conveyor belt.
So, are you a "will fly" or a "no fly"? There's not that much aviation physics to the myth (be sure to review the correct wording of the myth on page 1; post #1 of this thread/topic). All one has to know is that a plane moves by thrust (unlike a car) and has free spinning wheels (generally). Not much in-depth avionics there. The size of the conveyor won't matter (yeah, everyone make their own jokes). While it might make the experiemnt look "cooler", it cannot change the outcome since all conveyors, planes, and wheels are governed by the same physical laws (basic ones in this case). If you DON'T think the plane should fly and are planning an experiment of your own to prove that it won't, I urge you again to review the correct wording of the myth on the first page of this thread. If you DO think the plane should fly and just want to do a bigger experiment, then more power to ya! Later!  |

Aircraft have not changed much since the 80's...military or commercial. The Navy's latest plane...the F-18 was introduced to the fleet in the early 80's. The SH-60 also was introduced in the 80's. The same applies to USAF aiecraft....as well as COMMERCIAL AIRCRAFT...747, 757, 767, they all have been around a while. Aerodynamic tech was mastered by the 60's...all the latest developments have been in Avionics, Materials, Engines, and Stealth tech. Planes flew the same way in the 80's as they did in the 20's...and will fky in the future. |

A little question to no-fly guys.
There are 4 space crafts, all moving along the line between two stars - A and B. Space craft 1(SC1) measures the speed of SC2 and gets reading 20 mph towards star A. SC3 measures the speed of SC4 and also gets reading 20 mph towards star A. Question is are SC2 and SC4 moving in the same direction or in opposite directions?

Military/Commercial Pilots...with thaousands of hours would understand these scientific principles. There would never be a case of a Commercial Pilot/military pilot who would be a NO FLY |

Felai and p100Hawkeye, eh. I've seen they're posts. Friends of yours? I still haven't noticed where you actually say whether you believe the plane will fly or not. Later! |

WOW, do you have problems reading or what?
Here is what I said and what YOU quoted:
"The Fourth is the Belt's speed. For convience this will be RPMs converted to mph."
mph NOT rpm
No, I see you measure the belt's speed in RPM. And then convert it in mph, apparently for convenience. Well, I don't like that convenience. Convert the plane's speed from MPH to RPM for convenience.
What happened? Busy converting the plane's speed in RPM? Or, perhaps, you can't do that...
Life happened. Just some happens that we had so strong winds recently that damaged over a dozen shingles that needed replacing. the whole point of what was posted is a possible viewpoint of the 'no-fly' and YOU don't get to change that. Any changes you make invalidate any attempt you are making to dispute the argument. |

Actually, I frequent a Navy message board, and I've seen this question fool even winged aviators. Of course, they're quicker than most to realize their mistake and understand why the plane flies. |

Why would the plane be unable to move??? What has the switch done to prevent motion? If the plane moved then the speeds would NOT match. 
1st, Nothing 2nd, exactly |

MB History is being made in a bad way. There are currently 3-4 different threads going on...all about plane and conveyor belts. I have been away a while...and something has changed to create THIS BAD SITUATION.

That's not nice. I hate when life happens to me. |

I'm still waiting for the plane's speed in RPM or an explanation why you can't give it to me.

Yes...yes I can. But rather than re-write all my responses...since this thread began months ago...look uo c26bt34c. You will find many responses addres this issue
but can you counter what was said without changing any of the given information?

Maybe we need to look at this myth from a different angle.
If they replaced the conveyor belt with a giant snake....

NO...the problem is that most no-flys join this thread late. It has been going on for months now. But because MB changed the format of this site...IT HAS LED TO 3-4 DIFFERENT THREADS COVERING THE SAME SUBJECT. I have previously tried to "replace the conveyor" with ICE...or a hovercraft hovering over the belt...to demonstrate the minor effect friction plays in the equasion....MB needs to shut this down...or go back to the old website format. This aint working |

HALLELUJAH TO THAT BROTHER!!! I AGREE!!! But then Discovery chooses to air shows like Smash Lab. I don't think there's any hope at all of improvement here. Later! |

Really. What posts are these? I can't imagine a website where you could ask Naval Aviators...these questions. I suppose some would get it wrong...without thinking about it...but most would not be fooled. |

Here's a little diversion for you smart people who know everything. Rise, Sink or Stay the same?As far as fly or no fly I am getting my thoughts together to explain things to you youtube/iphone generation. |
