Hi Guys,
The site is by no means dormant, I try my best to update it every day where possible be it via gallery images, Police/AA aircraft info etc. I'll see if I can get today's Helitech photos on tonight.
All of the registrations on the AA/Police/CG pages should link to GINFO if you click on them.
EK01 you are right on both counts, UKP051 is Strathclyde's Callsign for communications with ATC and the like, however the 'In Force' callsign I believe to be Victor Mike 70. I will try my best to add all of the ATC callsigns this week to the Police pages, probably should have done this a while ago to save confusion.
Strathclyde have an EC135 backup aircraft as part of the contract; this is most likely as to why you will have seen G-BZRS flying around - G-SPAO was back down at Gloucester with Bond on maintenance, certainly on the 4th (Probably its annual). There is a photo on flickr of it if you want to look at it. It may well be back now, I don't know.
If you have any questions/comments please do not hesitate to contact me through the site.
Regards,
Dan.
