Deadlifter
Back in 2003 NATS withdrew an offer to a trainee who was 6ft 10 when it became clear that he could not use the NATS workstations without risking damaging his health. He took NATS to a tribunal who found in favour of NATS. They are likely to be very careful to ensure you can work confortably at the various NATS workstations but there are controllers of 6ft 5 and 6ft 6 who can.
