Spotted a EIN flt on the ground at Dublin tonight 23.50 showing 7777 squark code 
This passage is from Wikipedia on use of codes.
"7777:
military interception (US) ("Under no circumstances should a pilot of a civil aircraft operate the transponder on Code 7777. This code is reserved for military interceptor operations.")[17]
non-discrete code used by fixed test transponders (RABMs) to check correctness of radar stations (BITE). (US, Germany, Netherlands, Belgium, ...)
Is this another glitch I wonder or conected to US Presidential Visit
