That's not an accurate comparison because the plane hits a steel lattice exterior without decelerating visibly at all and then makes partial contact with a steel core and maybe some concrete and then allegedly blows up.

momentum is a vector quantity, it has direction. you express surprise that the plane did not decelerate (or twist, etc). this would entail transfer of momentum backward or sideways. instead all momentum was transferred to the building, forward.
-
it was a highly inelastic collision, as kinetic energy was transferred into heat, destroying the plane and the outer wall of the building. if the plane was more rigid, this energy might have been preserved and sent backward, decelerating the plane

this "official" analysis has detailed calculations http://web.mit.edu/civenv/wtc/PDFfiles/Chapter%20IV%20Aircraft%20Impact.pdf … but i just want to point out that 25% of the overall kinetic energy was expended into the aircraft itself, almost 1000 megajoulepic.twitter.com/3EbHH5C5kh
