Nothing official I'm aware of, but you could hand wave it as the explosion was noticed by someone, maybe a flying plane, whatever, and they investigated and found enough debris to assume the passengers didn't survive. It wasn't explicitly stated but then again the producers didn't really know if they were going to get more seasons at the time so it probably wasn't worth calling out.
I enjoy reading the articles. I think combining r/frugalmalefashion and r/malefashionadvice scopes would make sense for now, so I'd welcome deals, reviews, etc.
