So, the Sala Eclipse 500 was procured through Channel Jets then -

Problem is, where Channel Jets have a Guernsey based 2-REG operation (do they have a Guernsey AOC already?) what were they doing using an N-Reg aircraft (N531EA) on their AOC (assuming they have a valid Guernsey AOC). Does the Guernsey register allow for the substitution of any old privately-owned aircraft on any register onto one of their 2-REG AOC operations?
