Bomb vulching. That is my favourite AH sport after sniping GVs from 7k with 500 lbers (a Mossie XVI speciality).
A proper bomb vulch is done from alts of 6k AGL or higher for the complete WTF effect. Maximal satisfaction is attained when you drop the bomb about mid-runway so the enemy is already airborne and gets blasted mid-air while flying through the explosion radius.
