I found some bugs on the 30mm cannon and they're fixed now.And the floating ejection seat is available now.
Although it's named as a "HMF",it's a Light Attack Plane in fact.Although it's a light attact aircraft,it has powerful loads.This is based on a picture that is drawn by one of my friends(not the one before XD),and I'm helping him to turn it into "fact" in the game.
Instructions:
AG1:Abandon all wing loaded weapons(Caution:it can be activated in all situations,so be careful about this)
AG4:Eject
AG6:Canopy
AG7:Parachute
AG8:Lights
Please view the pictures to get the details about what the inside jobs stands for.Some buttons requires you to read the notes above them inside the game.
