<snip> But what if the Falcon S2 could be modified (as others have suggested) to have comparable dynamics to the BFS, and still support existing payloads? Here is a speculative 'Frankenstein' approach:3. Three strakes of a similar form to the BFS strakes, but containing extra nitrogen tanks and thrusters. The strakes could also have the BFS split body flaps mentioned (but not so far visualised) for additional control authority.
3. Bangabandhu-1 was not sent to a super-synchronous GTO, whilst BulgariaSat-1, a slightly heavier satellite was. Is that down to differing customer requirements?
2. Because Iridium-7s S1 burn is three seconds shorter, with higher overall throttle, its velocity is generally faster and at a lower altitude, so heating flux should be slightly greater. This is at odds with the extra TPS on GPS-III and Iridium-8, so I'm not sure what's going on there.

Note that same shape on the fairing tip is typical for any Fairing 1.0., which was used for Iridium-8 mission. Some other found Fairing 1.0. examples with this detail .. FHDemo, Intelsat35e, or SES9.In contrast with previous Iridium missions (Iridium-6 and 7), where have been used Fairing 2.0., with circular shape on the tip.The only exception is GPS-III mission, where Fairing 2.0. had black extra TPS.
Iridium 8 definitely has a cap piece on top of the fairing in the same place as the GPS-III mission, albeit in white instead of black. Different bolt-on fairing nose parts for different ascent profiles?
I don't think that Iridium-8 used extra TPS.
They had no crew and just a few hundred kg of cargo. There should have been literally tonnes of extra margin. Was it *all* used to reduce MaxQ?
