Question: Plane identified as "Blocked"
 

Just browsing FR24 and there is a plane with identification "Blocked" landing at Biggin Hill (UK). Origin was IAD (Washington Dulles). Any idea who/what this may be ?

N373GG

But what is "GG" at the end of a USA plane registration? Official government plane?

When you register an aircraft in the USA you can have any letter, or combination of two letters (apart from "I" or "O", for obvious reasons), at the end.

Perhaps the aircraft in question belongs to a horse racing fan. :O

Or an opera buff...

Funnily enough, I happened to see this aircraft descending into Biggin on Saturday evening while out for my walk...

I thought I read that you could ask to have the registration blocked if you had a good reason -

I believe you don't need a good reason, but I do not know why some are 'blocked' and others are just blank. Military aircraft tend to be hidden altogether.

All you need for FR24 is proof that you own an aircraft, and they will block it on demand.

I prefer to watch online using ADSB Exchange, who do not block any bizjets or military.
