To Mr. Lancair in charge of safety:
    Respectfully I am suggesting you review information on the link atl@atlinc.com.
    None of the recent posts re Shannon's accident focused on the actual cause of the fatality, but instead -- on the causes of the engine failure in-flight.
    The final cause of the fatality was fire. 
 
Terrence,
    I'm interested in pursuing this.   I actually have an aux tank built by fuelsafe which has foarm in it to manage flammability.   However, one of the other mailing list members commented that foarm makes it difficult to purge the water from a tank.   So that is one issue with foam.
    I'd like to know more about your check valve idea.
    I have a IVP which is probably a different problem than a 320 so my comments below reflect that.
 
    I have noted that most Lancair's that crash also burn enthusiastically but I don't know what the mechanism is.    I would guess:
    1) fuel lines rupture at the wing root.   Do you have a solution for that?   Seems like you would need a remote valve.
    2) fuel tank (wing) breaks and spills.   Foarm would help here but how do you replace it every 10 years?  ...and deal with the water. bladder inside wing would be problematic given the replacement problem and in the IV the number of ribs and spars that cut through the tank area.
