For what it is worth, a no explosion on impact, the 146, a relatively safe machine, ran out of fuel, or faulty fuel gauges (as with Alidair Viscount 700, in 1979) showing incorrect readings?? - witnesses saw it pass overhead with no engines turning ? maybe they cut it too fine circling around ? so sad. Having worked for VARIG, I know how this will affect Brazilian Football, and globally, so very sad R.I.P to all young and old lives lost in a preventable accident.
