As a ex-pat living here in the heart where ZS-RSA, alias B737 BBJ has been "reconstructed", seen MANY times by myself taxiing past the Jet Aviation hangar in Basel, have wondered...??? Luckily I am not paying the 50% tax money of previous to fund this....
And there are some other ZS-..... machines as well, from time to time.
Talk is cheap, money buys the whisky...
