As of May30 their flight plans are still showing up on CFMU and being activated. Here is this mornings movement:
08:35A SIH230 B734 EINN EHAM T 370 08:25 08:35E FI 08:35
Not 100% if it actually got airborne but the rtn sector is also in the system:
21:51E SIH229 B734 EHAM EINN I 360 20:05 20:20E
I am sure the remaining staff are working pretty hard this weekend to try to keep things going.
