DID THE DIGITAL PLANE IMAGE DECELERATE AT WTC 2?
By Rick Rajter - October 26, 2006
One of the major oddities of all WTC2 videos is the apparent lack of plane deceleration from many of the observed camera angles. The plane seems to fly in effortlessly, but then comes to a complete stop while inside (apparently violating conservation of momentum and energy). To the layman, these two conservation laws mean we should expect TWO major sources of slowdown when one object penetrates another:
• Energy is lost via dissipation as the intruding object breaks and destroys the impacted area into smaller pieces
• Energy is transferred to the broken pieces in the form of kinetic energy or gained velocity.
