Evening Alan,
If you are currently monitoring, you will see this for yourself. Currently on 'My Flights' is UTA5772 a B757-231 registered VP-BPB with c/n 28484 and Mode S of 4242CD. It's routing GMAD-UUDD but the accompanying photo is of a helicopter also registered VP-BPB. Now that's one heck of a flight for a helicopter !
