That is not true, we are told that they can perform special attacks, advanced rule versus basic rule.
Once you are out of the restriction that all attacks are shooting attacks there is nothing stating that a bombing run is a shooting attack. Furthermore the fact that many other special attacks are specifically described as shooting attacks and this one is not, tends to imply that a special attack from a shooting weapon being a shooting attack is not a given.
Saying that a special attack is a shooting attack when not declared so, from a weapon we are not even sure is a shooting weapon, seems a bit stretched.
