Good Job? Hats Off? Heroes?

Tail wagging the dog here I'm afraid.

To get an aircraft into that state you have to do silly things - like
flying with the radar off in the first place - ignoring echoes - ignoring
all the warnings you had in training about the foolhardiness of entering
a CB cell.

Then, once the ship is damaged - and by the way there are other antennae in the nose cone too - depending on aircraft type, the ILS GP antenna for
instance - you have to get it down and are a hero...

Over the years this has happenned to my knowledge to a Spanish DC-9 over Valencia - landed in Barcelona with hugely dented slats, radome off, opaque windows - all radio antennae gone and one engine out... also a Korean 747 over the Alps, which landed in a non surprisingly similar state in Zürich. (That one then, following minimum repairs by a Boeing team, later took off on a ferry flight without applying the Boeing recommended TO corrections and staggered off the runway end and over the church tower in Kloten).

Both these ships had flown into CB cells - the Spanish DC-9 knowingly ("It only looked like a small cell...") and the Korean with the radar off.

Thunderstorm cells can have hail as big as dinner plates. Apart from that they are full of supercooled water ready to ice you up and severe turbulence. Stay out of them and be a quiet hero!
