What organizations?

Do you have information to the contrary?

Decades of observation.

Efficiency and effectiveness (in terms of numbers of casualties)
aren't
usually terrorist objectives, especially at the expense of being
spectacular. Surviving the attack is seen as a negative outcome.

based on what information?

Decades of observation, and general knowledge of middle-eastern
terrorist groups' teachings and statements, which include the premise
that successful suicide missions guarantee blissful eternal afterlife.
Survival is failure. Everyone knows this.

Do you have information to the contrary?

btw - using a small aircraft isn't even particularly spectacular.

Driving a plane into something will ALWAYS be more spectacular than
driving a car or truck into something, even if it is less effective.
