Dems dumping candidates from the party ballot for being 'too Republican'
State Rep. John DeBerry, who has represented District 90 in the state House of Representatives for 26 years, has been voted off the August party primary ballot by the executive committee of the Tennessee Democratic Party. The committee, meeting online in virtual mode Wednesday, voted 41 to 18, with two abstentions, to oust DeBerry.
The board also acted to remove four other candidates from the party’s primary ballot. They were: William Frazier, in State House District 84 seat; Michael Minnis, state House district 93; M. LaTroy Alexandria-Williams, 9th Congressional District; and Tharon Chandler, U.S. Senate.
DeBerry’s comeuppance was long in coming. Democrats, including local ones, had been vocal for years about the businessman/minister’s tendency to vote as a de facto ally of Republicans on a variety of issues, notably on bills to outlaw abortion and to legalize taxpayer-supported private-school vouchers.
Michael Minnis, who filed to run for the Tennessee State House District 93 seat, was removed without a vote of the board.

"Aircraft use transponders to communicate to ATC their position and status. Some squawk codes are reserved, such as 7700 (emergency), 7600 (communication failure), 7500 (hijacking), 1202 (glider), 1200 (VFR), etc. One of these, 7777, is apparently used for "military interception." What does this mean in the United States? Under what circumstances would it be used on a civilian / military aircraft?
In countries outside of the US, 7777 may be used by test transponders (RABMs) to check correctness of radar stations (BITE). e.g. on top of a mountain.
In the US, it seems that it is used as well on active air defense missions without ATC clearance. This would mean that the interceptor aircraft would change it's squawk to 7777 for the military/civilian air traffic controller to see it properly (if not filtered out on civil radars).
Under no circumstances should a pilot of a civil aircraft operate the transponder on Code 7777. This code is reserved for military interceptor operations.
The ATC orders don't add anything useful and a lot of security procedures are classified, or at least not publicly available on faa.gov. But it seems from that information that a) 7777 is important for interception operations, and b) civilian pilots must not use 7777. That implies that 7777 is reserved for interceptor aircraft, not the aircraft being intercepted."
