re: Something HUGE and really scary going on with aviation. Pilot's squawking 7700 - Emergency

7700 is general emergency this happens in spurts from my experience. I have never had to control a major emergency,but I have had a few ranging from indicators in the cockpit coming on and doing more of a precautionary landing to someone front wheel not opening. I once had three in a month that i controlled and none after that for over a year. I can imagine that as more aircraft go back into service you will have small things come happen until they whole fleet is flying regularly again. If an aircraft is squawking 7500 than it is time to shite.
