“I had exactly the same thing happen to me on a flight out of LHR to YYZ on a 747-400. What caused it was a static discharge while climbing through snow showers at about 6000 feet on departure. There was a huge bang and flash followed by the wx radar failing. We leveled off at 10,000 feet and accelerated to 300 knots to see if there was any adverse effect. Since the aircraft felt perfectly normal we carried on to Toronto. As we approached the gate, the ramp hands were pointing at the nose. When we got off we saw that the radome was pushed in as if a huge fist had punched it in the nose. As it turned out the pressure from the rapidly heated and expnded air had done the damage. The radar antenna had jammed.”
In the absence of any other explanation at this stage this seem the most credible explanation.
