great idea. reminds me of something brains came up with on "THUNDERBIRDS" having a jettisonable fuel container so the gas wouldn't blow up on a crash landing.
IF you look back in history, foaming was part of emergency landing procedures many years ago, but it was stopped. It didn't do that much good, if the plane didnt land withing 15 minutes of foaming, it did very little, high protein foam is made from blood and guts of animals. low proteing foam doesn't stick around too much.
I wish you well. It may be a good engineering exercise but probably will go the way of the upstairs piano lounge on the early 747's.
