I would believe that the WWE would be operating the Challenger jet. I do not know what the RWY lengths are there but I would imagine that there would not be a chartered widebody in there. Usually WWE flies commercial aircraft except for Vince McMahon, Linda McMahon or the other executives within the company.
For the recent bout at Sheffield they used B727 N211DB which used EMA as its gateway.
I guess it could be the same machine again for the Nottingham bout - hopefully they use something different though
Some interesting finds there. If anybody could get some confirmed information, that would be great. The closest to Nottingham Ice Arena would be EMA, so it would make sense? Would love to get that photo, as I will be in attendence on Friday night.
