Come to think of it, it can't be that CI flight landing at IAH.

Instead, it's more likely to be the Saudi Arabian cargo flight SV2904 that departed 8:34p for BRU.

The Doubletree is under a mile straight off at the end of Runway 15L, and only an old plane like a 742 can produce so much noise. And a heavy cargo plane with full fuel load means pretty slow climb.
