1. Planes are really heavy
    A fully loaded A380 can weigh 1,268,000 lbs on takeoff. For context, that's more than 462 Honda Civics.
  2. The FAA requires airlines to keep an ashtray in plane bathrooms...
    ... even though smoking is not allowed.
  3. You can get off a plane fast, if you really need to.
    The FAA requires proof that passengers can get off a plane in 90 seconds or less.
  4. Modern twin engine jets can keep flying even if one the engines stops working.
    And if all engines stop, planes can still glide for a relatively long time.
  5. You're safer on a plane than in bed
