I've seen that documentary a couple of times and it irritates me to no end. All that preparation to get the thing just barely airworthy, and a mistake made in haste and hubris trashes the plane and the project in about five minutes. Not to mention two perfectly good engines, brought in just for that purpose, are now at the bottom of the frozen lake.
You mean four perfectly good engines?
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
