Hi Pete, thanks for the answers you were able to make!
That explains some of my doubts, every day you learn something new :)
With the plane I had the same way of thinking but I was not sure
Maybe this is as much of a question as a comment, but it seems to me that instead of cancelling the tabernacle entirely, Tommy could have reduced its price in a big way by reducing the scale of it. Whether it got him suspected of murder by anyone other than Luke, just plain cancelling the project would've been bad publicity for him. And keeping it going in Edna's honor would've been just the opposite thing.
