@junksciencemyle What does that have to do with efficiency? It only needed about 5% of its kinetic energy to do that.
@junksciencemyle There’s a detailed analysis of the energy transfers here: http://web.mit.edu/civenv/wtc/PDFfiles/Chapter IV Aircraft Impact.pdf …
@junksciencemyle And a practical demonstration of the principles here:

@junksciencemyle The paper you read explains how much energy was used up. What would that look like as a deceleration of the tail ... Read even more
