Ah, The Drama.
Everyone nowdays is so touchy about everything in this ridiculous sense of 'moral' consciousness.
As far as I can see, Glasses is not making 'fun' of the situation, He just wanted to establish a simple point, which as I can see seems to be the 'difficulty' of flying a 'warbird'.
And as unfortunate as the incident was, it in fact, happened. Past tense. Many die every day, and it just is, death, natural. Glasses is just taking the unfortunate event as an example to make a pretty simple point.
Just let it go, death happens. In this case it's being discussed by a stranger to indulge in an argument...
Godsakes... a freaking drama for everything.
