While overflying India at night at FL240 in a CL44 in the late 70,s, we found ourselves suddenly in the middle of a nasty Cb. Besides the rather bad turbulence we got hit by lightning : extremely loud bang, funny smell in the cockpit, both VORs gone, HF gone . Only 1 NDB still working. Diverting in Bombay (was called like this in those days) was elected not to be a good option under the circumstances, and we finally found Muscat on the other side with the help of daylight.
On the ground we found HF antenna physically missing and VOR antenna ripped off its mountings but still hanging there (Good cables)Frightening experience though...
