You're absolutely right. The hottest parts of the Earth I've been in are in and around the African Continent, the M.E., and the Persian Gulf. Even in "Spring" on a metal ship, temps can reach 130°+. One Spring/Summer, during a 6mth deployment aboard USS NIMITZ, we had to secure flight ops for the day because temps on the flat top reached 135+. And that happened on more than one occasion. We used to relish those unscheduled "no-fly" days, because even in 120° cloudless skies, moving at 20+ kts, with so many aircraft turning on the deck, the uniforms and equipment we wear on deck, it's brutally hot. Cranial Helmet with double ear protection, eye goggles, long sleeve turtle necks, float coats (inflatable life vests), gloves, trousers, boots. And that's outdoors, with wind coming across the deck at 35+ it's (for wing lift purposes). I can't imagine being stuck in a fucking non-insulated metal box during the day in those areas of the world. The clock is literally ticking away at an enormously fast speed re: "cargo spoilage."
