So much for a 2 minutes cool down at idle before shutdown.
That was likely allowed by a Papal dispensation and might explain the "Holy" white smoke.
Savoia just kidding, the white smoke was likely caused by the flight crew removal of electrical power before the compressor stopped turning thus re-opening the fuel valve (not the shut off) and allowing fuel to trickle from the high pressure engine driven fuel pump back into the (still hot) combustion chamber.
Mary, depending on "who" you are in Italy altitude restrictions are a mere suggestion.
Aaaniway, "Viva er Papa!" as any true Roman would say.
