The external museum aircraft are parked at the Northern end of the runway next to what I remember to also be the VIP area. I think there was an old Herc too. If you tour the national museums of Ecuador, Chile, and Argentina the Canberra gets pride of place in all three.
If you’ve landed into Quito, by the time you see that Canberra the thrust reversers are screaming and your heart is probably just starting to calm down!!!!!
