Hijacking a thread
 

I know that lots of guys are reluctant to hijack a thread, but I feel differently and do it often. Think of it as like a round table conversation that evolves as it goes on, touching on many things of interest, while also satisfying the original subject matter. I think this is one reason the Barn is so popular, "like a box of chocolates, you never know what you're going to get!"

Well put Allan.. Some people get their knickers all bunched up when thins don't go according to their way of thinking. From my point of view, if Ford made it, and it fits a later or earlier model, use it..

Re: Hijacking a thread (Sidebar on how to be nice)
 

There is hijacking... and there is subject drift. The first priority should be (and generally is) to answer the question or resolve whatever initiated the post. Hijacking by changing to an entirely different subject should be avoided as it really needs its own thread.
Subject drift can be fun. A question such as "Why does my 1936 pickup have a garnish molding on one window and not on the other?" Once answered "Early 1935 had garnish... late 1935-37 did not". This could easily drift to when the change occurred, why it occurred, and obscure details (perhaps the color of the primer on the inside of the molding).
Suggesting to a poster that a comment is a hijack is imho not really polite and is unnecessarily confrontational. A more positive comment may be that the (hijack) subject warrants its own thread, or to create a new thread if the subject drift has enough relevance to both be preserved and expanded upon, or identify drift that is not significant with a note on the title of the response "Sidebar ..." As I have done.

Karl, You make an excellent point. Subject drift is more what I was making reference to. A highjack would be more like some yahoo offering his car for sale on your thread about something on your car. So yes, "Subject Drift" is fun!

Re: Hijacking a thread
 

I am a retired guy with time on my hands, so I enjoy the round table conversations that evolve. On the other hand, is it fair to the original poster who asked a question for us to be diverting his thread onto unrelated topics?

As with most things in life, I see pros and cons to both sides of this question.

OK ..... "Subject Drift"! I love it ..... here goes!


What is the cause of this cloud above the airplane wing, usually seen while taking off?

Jay, this is a rare attribute and something to cultivate and be proud of. Those who reply to the original question without considering previous replies must lead a very dull life!

Re: Hijacking a thread
 

Coop, you bum, you highjacked my thread! :eek:

Re: Hijacking a thread
 

OK, now that Alan has VERY skillfully alluded to the fact that he does not care to share the answer, anyone else care to take a shot at it?

Re: Hijacking a thread
 

OK, I have the answer... That cloud is all in your head.

See, now you're bringing about "Subject Drift" again!

Is that 'spent fuel' vapor cloud :confused: just a wild guess ;)

Re: Hijacking a thread
 

Plausible guess, but not even close, Lanny.

HINT ..... Top of wing ONLY! (SOME OF YOU PILOT-GUYS must have a clue)

Not sure, but I saw the same thing in Maverick Top Gun, on the top of their wings.

Re: Hijacking a thread
 

Is this the con trail that some say the government is poisoning us with? ...And if they're poisoning us, how come they can't get the job done already?

Re: Hijacking a thread
 

Getting a little closer! A wing produces lift by having LESS PRESSURE on top of wing than on bottom.

Subject drift
What a great term. I'd like to think this is how "rodders" of the past exchanged information.

Re: Hijacking a thread
 

They're NOT poisoning us with contrails. Contrails are produced behind engines that produce HOT exhaust into EXTREME cold air, air that is extremely high in humidity. Gotta have that high humidity & extreme cold!

Re: Hijacking a thread
 

Low pressure above the wing causes moisture vapor in the air to condense out into liquid water droplets/fog. I've seen physics teachers do this by pulling a vacuum in a glass jar.

But I don't understand why lower pressure condenses water vapor. Maybe you can explain that bit of physics to us.
