Who is Asher Avidar from By the Rivers of Babylon and what is their importance?

Avidar is the hot headed pilot of Concorde 01. During the pre-flight meeting, he questions Teddy Laskov about who is in charge should a problem arise. Laskov informs him to follow orders. Avidar is not pleased with the response. During the hijacking of the two Concordes, Avidar decides to take a risk and fly quickly out of range of the radio controlled detonator held by Ahmed Rish in the Lear jet. He fails, and Rish blows up the Concorde.
