Schools out, the country shuts down and everyone goes to party! But are you sure that it was a B747-200? They only have one and that has a regular service to JFK.
We had this conversation before and you didnt listen to me then,
OCV isnt operated by SARF, neither is HZ124 or HZ123 (Which I actually understand is grounded) or any learjets. And where did you get the information that HM1B is a flying hospital! (look at its tailnumber history)
