I want to apologize for posting that explosion image if maybe you were working on the space shuttle or close to people in there.

Many years ago I came to know an industry where accidental hydrogen explosions were to be described as “rapid oxidation events” (ROE) for insurance paperwork. Somehow writing the word “explosion” would have made insurance costs explode !
There are strong (& more) reasons to disbelive commercial transport projects involving hydrogen as energy source (energy vector).

Thanks for your time and explanations.
