XML data

I need to research why position reports did not come in for a specific flight on the 3/10/18.
Important!

Maybe you have some more info for us?
Is it a militairy flight?
Which hight?
Location?

Can you provide some more details and what your query looked like?

HAL 452 SYD HNL 10 March - Missed positions after takeoff until exit of Australia oceanic airspace. Eventually picked it up again after NADI. Web page showed flight. XML did not.

For that call, it looks like you used GetHistoricalTrack when the aircraft was still in taxi. This would be the reason why no data was returned at that time.
