. . . And getting back to the thread; where the topic is leaky door seal and inop TCAS for a short hop from the west coast of Florida to the east coast of Florida.
Let's get real: How high would you need to go in a King Air to fly 150 miles?
I'd say no more than 10,000' [press not required] in non RVSM airspace [TCAS not required]. IFR or ATC flight following available.
It's just a statement of fact, not an attempt to vindicate the operator's alleged other violations.
