Not the best scenario if this gets the go ahead.
Although Signature would gain a Hangar nearer to their facility, would they keep their Hangar down near cargo apron or flog it to Harrods ? Airport get back earlier the existing Landmark area for parking orange jets as I believe is mentioned in long term airport development plans.
Can't think Signature would operate 2 separate ramps.
End result is less parking space for business jets.
