Can't say for sure that NJE are getting any BBJ's, but what I do know is that they held an exhibition/fam day for current customers at EGLF in early June. The main attraction being a BBJ which had a lot of interest shown in it by their current customer base.
Also TAG's plans for the airfield include enough hangarage for I believe it is 7 BBJ's with the expectation of NJE operating them regularly out of there in the future.
