Let me guess, assuming non American pilots have access to the same FDC NOTAMS, he (or she) forgot to read the following:
FDC 7/2992 FDC …SPECIAL NOTICE… THE IRANIAN GOVERNMENT HAS
ISSUED NOTAMS SPECIFIC TO RESTRICTED AREAS TO INCREASE THE RADIUS OF THE RESTRICTED AIRSPACE, CLOSE AIR CORRIDORS AND OPEN TEMPORARY AIR CORRIDORS TO MOVE CIVIL AIR TRAFFIC AWAY FROM THESE AREAS. DESPITE THESE SAFETY PRECAUTIONS, IRANIAN MILITARY ELEMENTS HAVE BEEN KNOWN TO FIRE AT CIVIL AIRCRAFT OPERATING NEAR OR ADJACENT TO RESTRICTED AREAS. AIRMEN ARE REMINDED TO REMAIN CURRENT ON ALL NOTAMS BEFORE OPERATING AN AIRCRAFT OVER IRAN, PARTICULARLY THOSE PERTAINING TO RESTRICTED AIRSPACE REQUIREMENTS.
The Dassault Falcon is a European-made private passenger business jet that resembles a Lear jet. It can seat a crew of two and as many as 10 passengers. It’s used for passenger transport, but also has military uses.
So does a C172?
Please remember the source of the article. 
The incident occurred on Sept 30/08 and was in fact a Hawker 800 chartered by JAS Cargoways of Hungary. The four passengers were Hungary Military personnel, and straying into Iranian airspace was said to be an administrative error. Country of registration of the Hawker is unknown, there are no Hawker 800’s registered in Hungary.

Since when does a Lear resemble a Falcon Jet??
Okay I know the source…CNN
Bunch of losers
When a Falcon 10 is parked next to a Lear 24, 3 am, light rain, foreign country, 2 six packs down and you need to get more cash from the lock box to continue the festivities for 2 more days. Then one might make the mistake, maybe.
To play Devil’s Advocate for a moment, they (CNN) might have meant that the resemblance was more along the lines of common (business) usage and overall passenger capacity rather than Falcons and Lears are twins.
The media isn’t always wrong, although that’s the way the smart money bets! 
I thought all small jets were Learjets and the small planes that always crash are Cessnas.
Hmmmm… Nah…the media is just that ignorant James…
All planes look alike. Two wings, a tail thingy, and some wheels. Hopefully a door that closes. 
No, you’re thinking of Cirrus! http://www.z4-forum.com/forum/images/smilies/3.gif
The Civilian’s Guide to Aircraft Recognition:
Small aircraft (propeller planes with one motor) are all Cessnas but for the occasional one that isn’t.
Big planes (jets) are all jumbo jets or Concordes, or possibly both.
Military aircraft are probably all stealths (B-2).
Smaller jets are all Learjets, but for the occasional one that isn’t.
I’m sure you meant that as a joke…
Of course . . . made it up on the spot. Should I remove it?
NEVER!
