Regarding any link between this incident and the more recent discovery of explosives in cargo shipments: it
is being looked into, according to the US deputy security advisor:
Dubai says no blast in September UPS plane crash - World News | Tri-City Herald : Mid-Columbia news
Dubai authorities ruled out "an explosion" or "detonation" - but then the Xmas Bomber of last year (tied to the Yemeni group suspected in the most recent explosive shipments) also failed to "explode" - simply set himself on fire. A bomb that fizzles can still ignite flammable surroundings. In his case, clothing. In a cargo plane....?
A possibility worth investigating? - yes. A probability? Not yet.
