Great read, thanks for sharing. The article is well-written by someone well-informed (and highly qualified); refreshing in this day and age. I work in aviation but don't actually read much of these, so it was nice surprise - the account of the flight did read a bit like an ASOR though!
Seems it's still just the batteries holding us back on electrified aircraft! Hopefully solid-state batteries will improve things.
Well, he's facing the other way, so who nose.
