There is more. One more. They are supposed to hug the east side of the river and they were right smack dab in the middle of it. By a major international airport that is Class B airspace.
Ceiling height for helicopters are 200 AGL. They crashed into the commercial jet, that has serious limitations at taking evasive action, especially while descending and landing, at 350 AGL. I don't care if they're military, they do not have the authority to not follow FAA guidelines when in controlled airspace. That airspace BELONGED to that commercial jet. So here is my question. Now that you know the ceiling is 200 feet AGL, what do you think happens if they follow that regulation?
