This could be a fun one to do, the century series aircraft.
The aircraft...
North American F-100 Super Sabre
McDonnell F-101 Voodoo
Convair F-102 Delta Dagger
Lockheed F-104 Starfighter
Republic F-105 Thunderchief
Convair F-106 Delta Dart
prototypes are all welcome for the sake of them being in the spirit of the GB and also to make it a more encompassing GB
but no whatifs
so we can build:
F100, f101, f102, f104, f105, f106, (and their prototypes)
and also prototypes:
xf103, yf107, xf108
