Not at all - we had the place to ourselves at our level other than another Seneca at FL65 doing the same as us.
There were 4 aircraft that departed Stornoway in the morning. Though as I understand it, there were quite a few 'Eclipse' chasers in the Shanwick OCA on designated routes (commercial).
I actually expected there to be tonnes of flights in and around the area, alas it was very quiet indeed!
