After a year of lack of my research I have finally found information of this mystery KLM aircraft in Planes@Plaza in Amsterdam Airport! So lets find out about this aircraft!
We have to go back to 1968. First I thought it looks like Fokker look however this aircraft is a McDonnell Douglas DC-9! it was new to Delta Air Lines on April 7th 1969 ex N3333L. In 10th June 1980 it brought over to Ozark Airlines in the US it was re-registered as N929L in May 1981. Finally it was handed over to Trans World Airlines (TWA) in October 26th 1986 till it was withdrawn in in 5th April 2001. The aircraft was ferried to Marana - Pinal Air Park, USA waiting to be scrapped which it did in 2007 but KLM was interested to buy half of the plane & preserved it at Amsterdam Schipol Airport in The Netherlands. As I said half was chopped up for scrap the only part you'll see inside is the cabin & the cockpit. After it arrived in Amsterdam in October 2007 all painted up in KLM livery it's on display and opened to the public in November 2007.
The biggest attraction for customers who shop in Amsterdam Airport is the engine. I seen a lot of people taking photos of them with the turbine engine in the background thinking they get sucked into the engine or be like a cabin crew I saw few that did.
We come into the cabin! There is nothing much to see inside because the right side has been cut open to see toys and aircraft models (This is a store) you can sit back, relax and enjoy your flight with KLM! There is a TV I can't remember what it is so it might be the history of KLM.
And finally we come into the cockpit! It's so typical 1960/70's look! This was hard to take a photo of the hole cockpit because it's pretty small plus there are kids who wan'ts to take a look. When I put the pilot seat belt on I had very hard time taking the seat belt off I was stuck for 15 mins till I know how to take the seat belt off!
If you are visiting Amsterdam, The Netherlands I highly recommend visiting Planes@Plaza to get in is free of charge or you can go to the viewing gallery upstairs where Fokker 100 is there.
