Firstly it appears to be in a school gym, secondly it has tape holding the left wing on, thirdly it is suppose to be a RQ-170.
RQ-170 drone has a 66 foot wing span. Given that a basket ball court is 94 feet this looks a tad small. Bill Sweetman the military aviation expert thinks it could be a mock up, or alternatively a scaled down low cost version. It doesn't display stealth features other than being a flying wing.
Personally I think if they turned it upside down it would have 'Airfix' printed on the belly.
If it is real then they have not captured anything that will give them the technology to take over the world.
I think it is useless for anything other than a bit of fun and propaganda.
I might send the Iranian government a link to my ebay sale of on Radio gear for model aircraft.
