A1775/11 = No-fy zone for CZ-3A 1st stage drop zone over NW Guangxi
A1776/11 = No-fly zone for CZ-3A fairing drop zone over South China Sea
A1777/11 = No-fly zone for CZ-3A 2nd stage over South China Sea

(Identical zones as for I4 back in July)

    First stage debris report here

    AFAIU,  the CZ-3A first stage debris were spotted near Bachang (八昌) village  (N242025E1055332) [misprinted as Bajiang (八江)], Badu  township, Tianlin county, Guangxi province, in a field within the preset drop zone,
    The location is about the same as for Compass-I3 1st stage debris and less than 5 km from both Compass-I1 and Compass-I2 1st stages impact  location.
    According to the article, it is the 6th 1st stage from Beidou satellites to fall within the Badu township area.

    Interesting to see how the propulsion section has torn away, leaving relatively intact propellant tanks.  I wonder if this is typical of what happens to other expendable launch vehicle first stages.
