As a PPL and SLF, the thing that most worries me from the report is that an airliner went missing and nobody looked for it or even showed any concern for many hours.
If I understand the situation from the report (sorry I've been away for 2 days and trying to catch up on the report + about 6 pages), at 3 minutes after 02.20 Senegal should have kicked off to Brazil that they had no contact (which they should have had 5 mins before 02.20 Z). It seems that hours later they almost thought AF447 had just flown past them without contact and reported next to Cape Verde.
If the ACARS should send out a routine position report every 15 mins, should AF not have noticed within 30 - 45 mins that AF447 was not reporting and kicked off ?
Whilst in the AF447 case this may have been entirely academic, in another case it may not be at all.
