Despite BREXIT uncertainty, the aerospace industries are increasing their reliance on EU nationals who now account for 10% of the workforce:

There were 285,000 people working in aerospace during the final quarter of 2017, of which 28,000 were EU nationals – up from 19,000 in the final quarter of 2016  and 16,000 at the time of the BREXIT vote. The increase in EU nationals was most pronounced amongst aerospace manufactures where representation almost doubled from around 6% to 10% over the period (Q1.16-Q4.17).
