Wrong. Please read the NTSB report before making such statements.

I have read the report, and I don't see where readability came in.

1705:53.4 APP KLM eight seven * zero five uh you are cleared to the
Papa Beacon climb to and maintain flight level nine zero right turn
after take-off proceed with heading zero four zero until intercepting
the three two five radial from Las Palmas VOR. (1706:08.2)

1706:09.6 KLM Ah roger, sir, we're cleared to the Papa Beacon flight
level nine zero, right turn out zero four zero until intercepting the
three two five and we're now (at take-off). (1706:17.9)

I think there was some confusion here. I wasn't saying that he never
heard ATC at all, just that the transmission confusion was due to the
heterodyne, not static or poor transmission quality.
