I have a photo showing a Citation II, Lear 55 and a Hawker 800XP all happily sharing SZD apron space together, and another with a rather smart Falcon 50 awaiting its passengers.
From the photo you know that Biz jets could land and take off at SZD.In regard to reopening SZD as a commercial airport it is totally irrelevant Are you suggesting using Biz Jets to run a commercial operation from the airport? It might be alright for some business travellers to use them and in some cases companies would use their own aircraft.but the cost to the general public would be prohibitive.It does not make sense to reopen the airport,it is just not a viable proposition.
