A momentous occasion! What astounds me is the sheer volume of revisions done on GTU-0. Things I noticed, besides the obvious flight test boom:
- Unpainted surfaces for flaperons, ailerons, rudders and horizontal tails. Maybe parts were revised/replaced?
- Unpainted area just behind the canopy. This is usually where conformal antennae reside. Test Pilot Barbaros Demirbaş mentioned data-link. The videos are low resolution, so I can't tell.
- Unpainted area around the pitot tubes. No idea what changed here.
- Aileron actuator fairing grew in size. Possibly the actuators were beefed up.
- Landing gears. We knew these were going to change for the maiden flight.
- New or reinforced canopy. We know some testing was done at Martin Baker, so this isn't surprising.
- IRST and EOTS placeholders plugged.
- Tail boom is missing. Drogue chute in its place.
Anything I missed?
