3. Wreck your plane
4. Destroy bedrock and fall out of the world

Additional context

It seems already on TODO but I'll post it anyway. When the block hardness is -1, the damage factor should changed to much higher value like 100 and don't destroy the block EntityDriveable.java line 1334

// Attack the part
if(!attackPart(p.part, DamageSource.IN_WALL, 
    blockHardness * blockHardness * (float)speed) && TeamsManager.driveablesBreakBlocks) {

    // And if it didn't die from the attack, break the block
    // TODO: [1.12] Heck
    // playAuxSFXAtEntity(null, 2001, pos, Block.getStateId(state));

    if(!world.isRemote){
        WorldServer worldServer = (WorldServer)world;
        destroyBlock(worldServer, pos, getDriver(), true);
    }
}
