Round 1
Reviewer 1 Report
The proposed paper is addressing an important area regarding public attitudes towards the increasing development of drone delivery services in everyday life. While there has been extensive statistical analysis of the data obtained there are some areas of the paper that could be tighter as outlined below.
Introduction:
Line 46 - There are many instances of health service delivery - Zipline in Africa is just one example.
There is no background about the case study city Medellin and why it is a suitable choice for the survey. Further how has Covid-19 affected the city and how might drone delivery services improve life there?
Are drones used in other capacities in the city (agriculture, leisure, commercial etc) and therefore how familiar are local people with drones? The context in which drones are used for delivery is crucial - trying to implement drones as a friendly delivery service in a region where they have been used to cary or drop bombs on civilians will change peoples perceptions. The theory on this has been explored by Gregoire Chamayou, 2013 (A theory of the drone) and Peckham and Sinha, 2019 (Anarchitectures of Health: Futures of the Biomedical Drone).
In the Materials and Methods section more information should be given about the selection criteria of participants and conduction of the survey. Are they regular citizens, business owners, age, gender...
One thing that I would like to see made clearer is what type of potential drone delivery services the survey participants were responding to. Health delivery services (essential services) might have a different answer profile to pizza delivery (convenience) for example.
Covid-19 relevance - to validate utilising Covid-19 as a pretext for the survey there needs to be pre Covid-19 comparative data as a baseline.
Why was qualitative data from the "open-ended questions" not presented? I think this is just as important if not more so than statistical analysis. Qualitative statements might have been better used to back up the statistics, particularly on issues of concern such as privacy and delivery risks.
The conclusion comes back again to Covid-19 but I don't think this has been tested specifically, this seems more of a general assumption. Overall the authors need to decide whether the data fits the title of the paper.
In summary the paper would benefit from some reorganisation and depth.

At the moment, the use of the drone service for the monitoring and mitigation of landslide risks in low-income settlements in the city is registered in the city in academic research, as well as support in the collection of data for thermal analysis of urban environments in the Valley of Bored. This information is included in the introduction in lines 53-60. |

Reviewer 2 Report
Factors associated with the adoption of drones for product delivery in the context of the COVID-19 pandemic in Medellín, Colombia
This study is interesting in that it focuses on drones that are currently the biggest issue in the diverse industries. There are limitations of the adoption of drones for product delivery, but I think the implications are not bad. The opinions and comments are illustrated as follows.
First, the reason for introducing drones for product delivery is unclear. For example, the authors mentioned that the introduction of drones for product delivery has accelerated due to COVID-19, but argue that drones should be introduced to reduce costs and increase work efficiency.
Second, in the current technological situation, drones are difficult to completely replace the current systems of delivery services. The authors must acknowledge this part.
Third, the introduction is too lengthy. It needs to be simplified.
Fourth, in the introduction part, it is necessary to emphasize the difference from existing studies.
Fifth, it is also necessary to explained perceived risks of drone food delivery services (e.g. financial risk, time risk, privacy risk, performance risk, and psychological risk).
Sixth, data analysis was performed properly and well.
Seventh, implications for the data analysis results are very insufficient. In particular, the authors need to think a lot about practical implications.

Introduction: The reason for introducing drones for product delivery is unclear. |
To justify the reason for the introduction of drones for the delivery of goods, it is explained that this serves as a contagion prevention measure in the delivery of goods at home in the city of Medellín. Also, it is left explicit in the research objective in lines 53-60. |

Reviewer 3 Report
Dear Authors,
The paper addresses an important and currently discussed topic of drone usage in parcels delivery which corresponds with the scope of the Drones journal. However, its quality is very poor and scientific soundness is very low. The paper lacks a crucial part - literature review, the research process is incomplete, the method and results are presented in dissatisfying way, the discussion part is limited as it is based only on a few previous papers. Therefore, in my opinion, the paper cannot be published in present form. Below I enclose more remarks:
1. Regarding the topic of article, the introduction (lines 48-53 ) should include the current data about e-commerce market, especially its growth during pandemic, while the authors cite outdated data from 3 years ago. It would be interesting to present the examples of drone usage in different parts of the world.
2. The introduction should briefly place the study in a broad context and present the research gap, highlight why this work is important and define the significance of work.
3. The article lacks of the well-developed literature review of similar research. The broad review of models used to analyse customer acceptance of technologies should be presented, while the authors present only one of them.
4. In Materials and Method Section the authors present constructs and variables in the proposed model. In this section the theoretical model should be presented in order to be confirmed in this research. On the basis of literature review, the authors should formulate the hypothesis, which should verified in this research.
5. The authors do not explain what is their contribution into the theory, if they used the original model of different authors (Yoo et al. , 2018). There is no information what are new aspects/elements of proposed model.
6. The characteristics of respondents should be presented in Materials and Method Section. There is no information about the way of respondence selection and if the research sample was representative.
7. The Discussion part is very poorly developed, as it contains the analysis and comparison of only four previous papers. The findings and their implications should be discussed in the broadest context possible. Future research directions may also be highlighted.
8. There is a lot of typos, technical mistakes e.g. source of data in tables should be indicated below the table; the Author Contribution section should be filed in properly.
9. The Literature section is very limited, as it contains only 25 papers.

Reviewer #3 |
Introduction: It would be interesting to present the examples of drone usage in different parts of the world. |
The use of drones to deliver medicines and samples to suspected COVID-19 patients in Africa is exposed. It is exposed how drones have been used in the city of Medellín to analyze the risks of landslides in low-income settlements and to collect data from urban heat islands. In the context of the pandemic, it is exposed how the use of these have helped to reduce the risk of infection of doctors or other medical personnel, also in disinfection in outdoor public service areas, as well as for monitoring and detection, social distancing, disinfection, data analysis, delivery of goods and medical supplies. As well as for home delivery of online orders, to reduce contact between people as a protective measure. Lines 50-68 and 105-126. |

Reviewer 3 Report
Although almost all my remarks were corrected, but regarding the quality of journal, the novelty and contribution of this study is not sufficient to publish the result. Another main problem is too small research sample, so the obtained results do not reflect the acceptence level of drones by society in Medellin.
