Controlled crash, my burro.
If Boeing designers didn't know the plane would fly...they wouldn't have been given the go-ahead to spend millions and millions of Boeing's money to build the sucker!  |
Dude... you people are entirely too uptight about stupid phrases... Yes, I said "you people" Take offense if you must.
The airplane was designed to do what? Fly. Was it designed to fall? No. Therefore, landing could be construed as a controlled crash. Feel smart yet?
The 747 happens to have been an experimental craft in terms of size. Although the airfoil design had been proven several times to be effective in generating MORE than enough lift, the overall mass and size of the plane led many to believe that it wouldn't actually lift off. "Many" being people whose opinions didn't actually count as far as those involved were concerned.
The idea that noone contested conventional knowledge is ludicrous at best. It happens all the time. There are always those who don't believe something, no matter how many times you tell them, or spell it out, or describe it, or provide even the most scientific of evidence toward it's eventual proof. They want to nitpick the smallest things, never grasping the big picture, so they're never proven "wrong".
The only people I consider stupid are the people who refuse to listen to anything, because they "know what they're talking about." The second you begin believing that noone can teach you anything, is the same second you begin being stupid. How many of you are "that guy"?
Kind of like your opinion on my sarcasm. Stop being so critical of everything... you just might learn something.
And by the way, the spark happens before TDC, making the full combustion event fulminate JUST posterior to TDC. If it fulminated AT TDC, the result could cause the piston to attempt to fight it's direction reversal, bending a connecting rod. Best case scenario is that the combustion event fulminates somewhat ATDC, while the spark event occurs somewhat BTDC.
